AIM: Prior structural magnetic resonance imaging (MRI) studies of attention-deficit/hyperactivity disorder (ADHD) have primarily focused on clinically diagnosed samples, whereas the neuroanatomical correlates of dimensional ADHD traits in healthy young adults (aged 18-27 years) remain insufficiently characterized, and it is unclear whether neuroanatomical patterns reported in clinically diagnosed samples generalize to subclinical trait variability in young adulthood. We therefore examined whole-brain voxelwise associations between gray matter volume (GMV) and the Conners' Adult ADHD Rating Scales (CAARS) Hyperactivity/Restlessness subscale as the primary analysis, and evaluated associations with other CAARS scales on an exploratory basis, using voxel-based morphometry (VBM). METHODS: Participants were 534 healthy young adults (304 males, 230 females; aged 18-27 years) without an ADHD diagnosis. ADHD traits were assessed using CAARS. High-resolution T1-weighted structural MRI data were acquired on a 3-Tesla scanner. GMV was analyzed using VBM implemented in SPM12. Voxelwise multiple-regression analyses were conducted, with Hyperactivity/Restlessness as the primary scale of interest and other CAARS scales examined in separate exploratory models. Statistical significance was set at p < 0.05 (cluster-level family-wise error [FWE]-corrected), using a voxelwise cluster-forming threshold of p < 0.001 (uncorrected). RESULTS: GMV in the right dorsolateral prefrontal cortex (DLPFC) showed a small but statistically significant positive association with Hyperactivity/Restlessness scores (cluster-level FWE-corrected p = 0.017). No significant associations were observed for other CAARS subscales, and no significant sex-stratified effects were detected. CONCLUSION: These findings are consistent with a dimensional perspective on ADHD-related traits and suggest that interindividual differences in Hyperactivity/Restlessness may be reflected in subtle GMV variation in the right DLPFC among healthy young adults. Further multimodal and longitudinal studies are warranted to clarify developmental and mechanistic interpretations.

BACKGROUND: Although exercise can help prevent age-related cognitive decline, the mechanisms underlying its effects on cognition, immune function remain unclear. Therefore, this study comprehensively examined the effects of circuit training on cognitive function, and the plasma proteome in middle-aged to older women. METHODS: Forty-eight women were assigned to either a four-month circuit training program (n = 23, exercising more than twice per week) or control group (n = 25). Cognitive function was assessed using Stroop, Flanker, N-back, and source memory tasks. Statistical analyses were performed using linear mixed-effects models with Type III analysis of variance. The plasma proteome was measured using Olink technology (1,098 proteins). Proteomic patterns were explored using orthogonal partial least squares discriminant analysis (OPLS-DA). Furthermore, between-group comparisons of protein changes (post-baseline differences) were performed using unpaired t-tests. For functional annotation, significantly altered proteins (identified by volcano plot analysis) were subjected to pathway enrichment analyses. RESULTS: Within-group changes in Stroop interference and d-prime were observed in the circuit training intervention group. Furthermore, the proteins significantly elevated in the exercise intervention group were functionally categorized into anti-inflammatory and immunosuppressive pathways (LRRC25, IL10RA), angiogenesis and tissue remodeling (PROK1, TNFRSF12A), and immune cell activation (CD7). However, no protein-cognition associations remained significant after FDR correction. CONCLUSIONS: This open-label randomized controlled trial provides preliminary evidence that a 4-month circuit training intervention may improve selected cognitive outcomes and alter circulating proteins related to immune, inflammatory, and carbohydrate-binding functions in middle-aged and older women. However, protein-cognition associations did not remain significant after FDR correction. These findings should be interpreted as hypothesis-generating and require confirmation in larger studies with integrated cognitive and molecular analyses.

PURPOSE: This study examined the neural correlates in functional brain connectivity common to subjective and objective sleepiness. Because functional connectivity can be measured at rest and during tasks, it is well suited for exploring the commonalities between sleepiness during psychomotor vigilance task (PVT) and at rest with measurement of The Karolinska Sleepiness Scale (KSS). Serial resting and task-based fMRI measurements across various states of arousal may reveal a common neural substrate that does not vary with task demands. The neural basis shared by the PVT, an objective measure highly sensitive to sleep debt, and subjective reports of sleepiness may be robust markers for sleepiness and contribute to an improved understanding of the brain mechanisms underlying sleepiness. PARTICIPANTS AND METHODS: The participants were 16 healthy right-handed (self-reported) adult men who, after a 2-week home examination, participated in a 14-day/13-night experiment that included 9 days of extended sleep (12 h per night), followed by one night of total sleep deprivation (0 h), and recovery sleep. KSS and the PVT were used as subjective and objective measures of sleepiness, respectively. Functional connectivity in the brain during each condition were measured using fMRI. In particular, the association between the inverse of the reaction time to the PVT task and resting-state functional connectivity was analyzed using a general linear mixed model. RESULTS: Functional connectivity in six pairs of regions commonly associated with the KSS and PVT were identified. These included the anterior cingulate cortex-posterior cingulate cortex (part of the default mode network) and thalamus-middle temporal cortex, indicating that connectivity in these brain regions were strongly associated with sleepiness. CONCLUSION: These results suggest a common neural substrate for subjective and objective sleepiness, which may be an important indicator of sleepiness. In addition, the functional connectivity between the thalamus and the middle temporal cortex may be a new network that deserves further attention in sleep research. The results of this study provide valuable insights into the effects of sleep deprivation and total sleep deprivation experienced in daily life on the brain and offer a new perspective on the expression of sleepiness in the brain.

Abstract Background Long-term exercise is increasingly considered an effective strategy to counteract cognitive decline associated with aging. Previous studies have indicated that circuit training exercises integrating aerobic and resistance modalities positively affect cognitive function. Furthermore, a growing body of evidence suggests that long-term exercise alters the gut microbiota, leading to an optimal environment for cognitive enhancement. Recent empirical evidence suggests that exercise plays a significant role in modulating aging-control factors at the protein level. Although the interaction between exercise and cognitive function is multifaceted, most studies have only examined a direct pathway from exercise to cognitive function. Therefore, this study aims to elucidate the effects of long-term circuit training on cognitive function through a comprehensive analysis of factors such as gut microbiota and proteins related to aging control. Methods A total of fifty-one participants will be randomly assigned to either the circuit training or waitlist control group. The intervention group will participate in a circuit training program developed by Curves Japan Co., Ltd. two to three times weekly for 16 weeks. The control group will continue their usual daily routines without participating in any new active lifestyle program. The participants will undergo cognitive assessments at baseline and after the intervention. Fecal and blood samples for protein analysis will be collected before and after the intervention. The effect of exercise on cognition will be analyzed by comparing the measured outcomes before and after the intervention. The associations among these outcomes will be assessed using a linear mixed model and structural equation modeling approaches. Discussion This study aims to provide the first insights into the comprehensive effects of exercise on cognitive function from the perspectives of gut microbiota and aging control. The findings are expected to contribute to improving brain health and combating age-related cognitive decline. Furthermore, the findings may help establish new guidelines for future studies on the relationship between exercise and cognitive function.

PURPOSE: The aim of this study was to develop a novel approach that enhanced diagnostic accuracy in the diagnosis of mild cognitive impairment (MCI) and early Alzheimer's disease (AD) using cerebral perfusion SPECT by minimizing artifacts caused by cerebral atrophy. MATERIALS AND METHODS: [99mTc]-ECD and SPECT studies were performed on 15 cognitively normal patients, 40 patients with MCI, and 16 patients with AD. SPECT images were compared using SPM. The atrophy correction method was incorporated to reduce artifacts through the MRI masking procedure. Regional Z-score, percent extent, and atrophy correction rate were obtained and compared. The Z-score mapping program was structured as a single package that ran semi-automatically. RESULTS: The method significantly reduced regional Z-score in most regions, leading to improved estimates. The mean atrophy correction rate ranged from 10.4 to 12.0%. In MCI and AD, the convexities of the frontal and parietal lobes and the posterior medial cerebrum were particularly sensitive to cerebral atrophy, and the Z-scores were overestimated, whereas the posterior cingulate cortex and the cerebellum were less sensitive. The diagnostic accuracy for MCI increased from 67 to 69% and for AD from 78 to 82%. CONCLUSION: The proposed approach provided more precise Z-scores with less over- or underestimation, artifacts, and improved diagnostic accuracy, being recommended for clinical studies.

INTRODUCTION: Body-image disturbance is a major factor in the development of eating disorders, especially among young women. There are two main components: perceptual disturbance, characterized by a discrepancy between perceived and actual body size, and affective disturbance, characterized by a discrepancy between perceived and ideal body size. Interventions targeting body-image disturbance ask individuals to describe their own body without using negative expressions when either viewing it in a mirror or imagining it. Despite the importance of reducing body-image disturbance, its neural mechanisms remain unclear. Here we investigated the changes in neural responses before and after an intervention. We hypothesized that neural responses correlated with the degree of body-image disturbance would also be related to its reduction, i.e., a reduction in perceptual and affective disturbances would be related to changes in attentional and socio-cognitive processing, respectively. METHODS: Twenty-eight young adult women without known psychiatric disorders underwent a single 40-min intervention. Participants completed tasks before and after the intervention, in which they estimated their perceived and ideal body sizes using distorted silhouette images to measure body-image disturbance. We analyzed the behavioral and neural responses of participants during the tasks. RESULTS: The intervention did not significantly reduce body-image disturbance. Analysis of individual differences showed distinct changes in neural responses for each type of disturbance. A decrease in perceptual disturbance was associated with bodily visuospatial processing: increased activation in the left superior parietal lobule, bilateral occipital gyri, and right cuneus. Reduced affective disturbance was associated with socio-cognitive processing; decreased activation in the right temporoparietal junction, and increased functional connectivity between the left extrastriate body area and the right precuneus. DISCUSSION: We identified distinct neural mechanisms (bodily visuospatial and socio-cognitive processing) associated with the reduction in each component of body-image disturbance. Our results imply that different neural mechanisms are related to reduced perceptual disturbance and the expression thereof, whereas similar neural mechanisms are related to the reduction and expression of affective disturbance. Considering the small sample size of this study, our results should be regarded as preliminary.

Public facilities that have NIMBY (not in my backyard) structure involve both a social dilemma, in which individuals' decisions to prevent the worst outcomes for themselves undermine the public interest, and a moral dilemma focused on the majority versus the minority. This study examined the cognitive-neural processes in judging whether to prioritize the site residents or the citizenry as a whole within the context of NIMBY. Our ROIs were the right angular gyrus being related to concern about the worst possible outcomes for others and oneself, the amygdala associating with emotional aversion to prioritizing the majority, and the vmPFC, which integrates the aversion into "all things considered" judgments. As a result of comparing ingroup conditions for which a NIMBY facility may make participants worst-off position and outgroup conditions for which this possibility is denied, the right angular gyrus was activated in both conditions. The amygdala was activated only in the ingroup, and the vmPFC exhibited a stronger tendency in the ingroup. We concluded that the cognitive-neural processes in judgments on NIMBY facilities are common to both decision-making to avoid the worst-off position for others and for oneself and moral judgments between the majority and the minority.

The COVID-19 pandemic required people to adapt rapidly to the digital transformation of society for social survival, which highlighted the divide between those who can and cannot digitalize. Previous studies investigated factors promoting adaptation to digitalization; however, outcomes from adaptation to a digitalized society have not been sorted into a parsimonious model, even though there should be several multifaceted outcomes (e.g., usefulness, economic profit, and social outcome), each of which is promoted by different factors. If the effects of individual background factors can be revealed, including the technical-environment and survival-relevant personality in relation to each outcome, it would help in the creation of a society where more people play an active role by adapting to digitalization. This study aimed to construct such a model by identifying major outcomes gained in a digitalized society and investigating individual factors that contribute to the degree of gain of each of these outcomes. Five dimensions were identified by online surveys and factor analysis: Socialization (outcomes derived from new social connections created online), Space–time (freedom from time and space constraints), Economics (monetary outcome by using digital services), and Information (ease and amount of acquisition of information) were the positive outcomes, whereas Loneliness (feelings of not being able to keep up with digitization) was identified as a negative outcome. We determined that technical-environmental factors (e.g., familiarity with digital techniques and the amount of money that can be used for digitalization) facilitated gain in four positive outcomes. Notably, leadership and conscientiousness facilitated the Socialization gain while etiquette suppressed it. These factors’ effects would reflect the importance of a personality trait prioritizing construction and maintenance of social relationships. This study implies that material outcomes (i.e., Space–time, Economics, and Information) are promoted by technical-environmental support, whereas social outcomes may additionally require motivation and a positive attitude for purposeful social engagement.

The Tohoku Medical Megabank Brain Magnetic Resonance Imaging Study (TMM Brain MRI Study) was established to collect multimodal information through neuroimaging and neuropsychological assessments to evaluate the cognitive function and mental health of residents who experienced the Great East Japan Earthquake (GEJE) and associated tsunami. The study also aimed to promote advances in personalized healthcare and medicine related to mental health and cognitive function among the general population. We recruited participants for the first (baseline) survey starting in July 2014, enrolling individuals who were participating in either the TMM Community-Based Cohort Study (TMM CommCohort Study) or the TMM Birth and Three-Generation Cohort Study (TMM BirThree Cohort Study). We collected multiple magnetic resonance imaging (MRI) sequences, including 3D T1-weighted sequences, magnetic resonance angiography (MRA), diffusion tensor imaging (DTI), pseudo-continuous arterial spin labeling (pCASL), and three-dimensional fluid-attenuated inversion recovery (FLAIR) sequences. To assess neuropsychological status, we used both questionnaire- and interview-based rating scales. The former assessments included the Tri-axial Coping Scale, Impact of Event Scale in Japanese, Profile of Mood States, and 15-item Depression, Anxiety, and Stress Scale, whereas the latter assessments included the Mini-Mental State Examination, Japanese version. A total of 12,164 individuals were recruited for the first (baseline) survey, including those unable to complete all assessments. In parallel, we returned the MRI results to the participants and subsequently shared the MRI data through the TMM Biobank. At present, the second (first follow-up) survey of the study started in October 2019 is underway. In this study, we established a large and comprehensive database that included robust neuroimaging data as well as psychological and cognitive assessment data. In combination with genomic and omics data already contained in the TMM Biobank database, these data could provide new insights into the relationships of pathological processes with neuropsychological disorders, including age-related cognitive impairment.

Introduction Coping with mortality threat, a psychological threat unique to humans and distinct from general emotional distress, is traditionally characterized by immediate suppression and prolonged worldview defense within the framework of the influential terror management theory (TMT). Views regarding the personality-trait concepts for this coping capacity diverge: some favor a broad definition based on general psychological attitudes (e.g., hardiness), while others prefer a narrow definition linked to interpersonal attitudes related to social coalition (e.g., attachment style and self-transcendence). Methods Using functional MRI, we presented healthy older participants with death-related words and explored correlations between the neural responses to mortality threat and the factor scores of the Power to Live questionnaire, which measures eight resilience-related psychobehavioral traits. Results We observed a significant association between the factor score and a neural response only for leadership; individuals with a high leadership score exhibited reduced neural response to mortality salience in the right inferior parietal lobule. Discussion Within the TMT framework, our findings align with the concept of the immediate suppression of death-thought accessibility associated with a secure attachment style, a trait conceptually linked to leadership. These findings highlight the unique role for the narrowly defined social-coalitional trait during the immediate stage of the coping process with mortality salience, in contrast to the broadly defined resilience-related personality traits associated with a prolonged worldview defense process. The deterioration of this coping process could constitute a distinct aspect of psychopathology, separate from dysfunction in general emotion regulation.

Recent psychological and neuroimaging studies on altruism–egoism dilemmas have promoted our understanding of the processes underlying altruistic motivation; however, little attention has been paid to the egoistic counter-dynamics that prompt hesitancy to help. These counter-dynamics may involve the construction of reasons not to help based on contextual elaboration and explain individual differences in the tendency to help others in daily life. In this functional magnetic resonance imaging (fMRI) study, we explored the neural correlates of altruism–egoism dilemmas during empathy-driven helping decisions, with particular attention to the counter-dynamics related to individual helping tendency traits. We used two context-rich helping decision scenarios. In the empathy dilemma (Emp) scenario, empathy-driven motivation to help a poor person was associated with a cost, whereas in the economic-dilemma (Eco) scenario, self-beneficial motivation to help a non-poor person was associated with a cost. Our results showed activation of the right anterior prefrontal cortices, supramarginal gyrus, and posterior cingulate cortex (PCC) for the altruism–egoism dilemma (i.e., Emp &gt; Eco). A significant negative effect of the helping tendency trait score was observed on PCC activation; interestingly, this effect was observed for both Emp and Eco dilemmas. The identified neural correlates of altruism–egoism dilemmas appear to be related to the construction of decision reasons based on contextual elaboration in naturalistic situations. In contrast to the classical view, our results suggest a two-stage model that includes an altruistic helping decision followed by counter-dynamics to determine the individual helping tendency.

Body-image disturbance is a core feature of eating disorders and can predict their development in healthy individuals. There are two components of body-image disturbance: perceptual disturbance (associated with overestimation of body size) and affective disturbance (associated with body dissatisfaction). Previous behavioral studies have hypothesized that attention to particular body parts and negative body-related emotions resulting from social pressure are associated with the respective degrees of perceptual and affective disturbance; however, the neural representations that underlie this hypothesis have not been elucidated. Thus, this study investigated the brain regions and connectivity associated with the degree of body-image disturbance. Specifically, we examined the brain activations associated with participants' estimation of the width of their actual and ideal bodies; we sought to determine which brain regions and functional connectivity from body-related visual processing regions were correlated with the degree of each component of body-image disturbance. The degree of perceptual disturbance was positively correlated with excessive width-dependent brain activations in the left anterior cingulate cortex when estimating one's body size; it was positively correlated with the functional connectivity between the left extrastriate body area and left anterior insula. The degree of affective disturbance was positively correlated with excessive width-dependent brain activation in the right temporoparietal junction and negatively correlated with functional connectivity between the left extrastriate body area and right precuneus when estimating one's ideal body size. These results support the hypothesis that perceptual disturbance is associated with attentional processing, whereas affective disturbance is associated with social processing.

The number of older adults is increasing globally. Aging is associated with cognitive and sensory decline. Additionally, declined auditory performance and cognitive function affect the quality of life of older adults. Therefore, it is important to develop an intervention method to improve both auditory and cognitive performances. The current study aimed to investigate the beneficial effects of auditory and cognitive training on auditory ability and cognitive functions in healthy older adults. Fifty healthy older adults were randomly divided into four training groups-an auditory-cognitive training group (AC training; n = 13), an auditory training group (A training; n = 13), a cognitive training group (C training; n = 14), and an active control group (n = 12). During the training period, we reduced the sound intensity level in AC and A training groups and increase training task difficulty in AC, A, and C training groups based on participants' performance. Cognitive function measures [digit-cancelation test (D-CAT); logical memory (LM); digit span (DS)], auditory measures [pure-tone audiometry (PTA)], and magnetic resonance imaging (MRI) scans were performed before and after the training periods. We found three key findings. First, the AC training group showed difference between other training groups (A, C, and active control training groups) in regional gray matter volume (rGMV) in the right dorsolateral prefrontal cortex, the left inferior temporal gyrus (L. ITG), the left superior frontal gyrus, the left orbitofrontal cortex, the right cerebellum (lobule 7 Crus 1). Second, the auditory training factor groups (ATFGs, the AC and A training groups) improved auditory measures and increased the rGMV and functional connectivity (FC) in the left temporal pole compared to the non-ATFGs (the C training group and active control group). Third, the cognitive training factor groups (CTFGs; the AC and C training groups) showed statistically significant improvement in cognitive performances in LM and D-CAT compared to the non-CTFGs (the A training group and active control group). Therefore, the auditory training factor and cognitive training factor would be useful in enhancing the quality of life of older adults. The current AC training study, the plasticity of the brain structure was observed after 4 weeks of training.

Distracted attention is considered responsible for most car accidents, and many functional magnetic resonance imaging (fMRI) researchers have addressed its neural correlates using a car-driving simulator. Previous studies, however, have not directly addressed safe driving performance and did not place pedestrians in the simulator environment. In this fMRI study, we simulated a pedestrian-rich environment to explore the neural correlates of three types of safe driving performance: accurate lane-keeping during driving (driving accuracy), the braking response to a preceding car, and the braking response to a crossing pedestrian. Activation of the bilateral frontoparietal control network predicted high driving accuracy. On the other hand, activation of the left posterior and right anterior superior temporal sulci preceding a sudden pedestrian crossing predicted a slow braking response. The results suggest the involvement of different cognitive processes in different components of driving safety: the facilitatory effect of maintained attention on driving accuracy and the distracting effect of social-cognitive processes on the braking response to pedestrians.

The concept of alexithymia has garnered much attention in an attempt to understand the psychological mechanisms underlying the experience of feeling an emotion. In this study, we aimed to understand how the interoceptive processing in an emotional context relates to problems of alexithymia in recognizing self-emotions. Therefore, we prepared experimental conditions to induce emotional awareness based on interoceptive information. As such, we asked participants to be aware of interoception under an anxiety-generating situation anticipating pain, having them evaluate their subjective anxiety levels in this context. High alexithymia participants showed attenuated functional connectivity within their 'interoception network', particularly between the insula and the somatosensory areas when they focused on interoception. In contrast, they had enhanced functional connectivity between these regions when they focused on their anxiety about pain. Although access to somatic information is supposed to be more strongly activated while attending to interoception in the context of primary sensory processing, high alexithymia individuals were biased as this process was activated when they felt emotions, suggesting they recognize primitive and unprocessed bodily sensations as emotions. The paradoxical somatic information processing may reflect their brain function pathology for feeling emotions and their difficulty with context-dependent emotional control.

PURPOSE: The thalamus, the region that forms the attentional network and transmits external sensory signals to the entire brain, is important for sleepiness. Herein, we examined the relationship between activity in the thalamus-seed brain network and subjective sleepiness. MATERIALS AND METHODS: Fifteen healthy male participants underwent an experiment comprising a baseline evaluation and two successive interventions, a 9-day sleep extension followed by 1-night total sleep deprivation. Pre- and post-intervention tests included the Karolinska sleepiness scale and neuroimaging for arterial spin labeling and functional connectivity. We examined the association between subjective sleepiness and the functional magnetic resonance imaging indices. RESULTS: The functional connectivity between the left or right thalamus and various brain regions displayed a significant negative association with subjective sleepiness, and the functional connectivity between the left and right thalamus displayed a significant positive association with subjective sleepiness. The graph theory analysis indicated that the number of positive functional connectivity related to the thalamus showed a strong negative association with subjective sleepiness, and conversely, the number of negative functional connectivity showed a positive association with subjective sleepiness. Arterial spin labeling analysis indicated that the blood flow in both the left and right thalami was significantly negatively associated with subjective sleepiness. Functional connectivity between the anterior cingulate cortex and salience network areas of the left insular cortex, and that between the anterior and posterior cingulate cortices showed a strong positive and negative association with subjective sleepiness, respectively. CONCLUSION: Subjective sleepiness and the thalamic-cortical network dynamics are strongly related, indicating the application of graph theory to study sleepiness and consciousness. These results also demonstrate that resting functional connectivity largely reflects the "state" of the subject, suggesting that the control of sleep and conscious states is essential when using functional magnetic resonance imaging indices as biomarkers.

In modern society, many people have insomnia. Chronic insomnia has been noted as a risk factor for depression. However, there are few functional imaging studies of the brain on affective functions in chronic insomnia. This study aimed to investigate brain activities induced by emotional stimuli in chronic insomnia patients. Fifteen patients with primary insomnia and 30 age and gender matched healthy controls participated in this study. Both groups were presented images of fearful, happy, and neutral expressions consciously and non-consciously while undergoing MRI to compare the activity in regions of the brain responsible for emotions. Conscious presentation of the Happy-Neutral contrast showed significantly lower activation in the right orbitofrontal cortex of patients compared to healthy controls. The Happy-Neutral contrast presented in a non-conscious manner resulted in significantly lower activation of the ventral striatum, right insula, putamen, orbitofrontal cortex and ventral tegmental area in patients compared to healthy controls. Our findings revealed that responsiveness to positive emotional stimuli were decreased in insomniac patients. Specifically, brain networks associated with rewards and processing positive emotions showed decreased responsiveness to happy emotions especially for non-conscious image. The magnitude of activity in these areas also correlated with severity of insomnia, even after controlling for depression scale scores. These findings suggest that insomnia induces an affective functional disorder through an underlying mechanism of decreased sensitivity in the regions of the brain responsible for emotions and rewards to positive emotional stimuli.

<title>Abstract</title> Facing one’s own death and managing the fear of death are important existential issues, particularly in older populations. Although recent functional magnetic resonance imaging (fMRI) studies have investigated brain responses to death-related stimuli, none has examined whether this brain activation was specific to one’s own death or how it was related to dispositional fear of death. In this study, during fMRI, 34 elderly participants (aged, 60–72 years) were presented with either death-related or death-unrelated negative words and asked to evaluate the relevance of these words to the “self” or the “other.” The results showed that only the left supplementary motor area (SMA) was selectively activated during self-relevant judgments of death-related words. Regression analyses of the effect of fear of death on brain activation during death-related thoughts identified a significant negative linear correlation in the right supramarginal gyrus (SMG) and an inverted-U-shaped correlation in the posterior cingulate cortex (PCC) only during self-relevant judgments. Our results suggest potential involvement of the SMA in the existential aspect of thoughts of death. The distinct fear-of-death-dependent responses in the SMG and PCC may reflect fear-associated distancing of the physical self and the processing of death-related thoughts as a self-relevant future agenda, respectively.

Neuropsychology and neuroimaging studies provide distinct views on the key neural underpinnings of social scene understanding (SSU): the amygdala and multimodal neocortical areas such as the posterior superior temporal sulcus (pSTS), respectively. This apparent incongruity may stem from the difference in the assumed cognitive processes of the situation-response association and the integrative or creative processing of social information. To examine the neural correlates of different SSU types using functional magnetic resonance imaging (fMRI), we devised a clothing recommendation task in three types of client's standpoint. Situation-response association was induced by a situation-congruent standpoint (ecological SSU), whereas the integrative and creative processing of social information was elicited by a lack and situation incongruence of the standpoint (perceptual and elaborative SSUs, respectively). Activation characteristic of the ecological SSU was identified in the right amygdala, while that of the perceptual SSU and elaborative SSU demand was identified in the right pSTS and left middle temporal gyrus (MTG), respectively. Thus, the current results provide evidence for the conceptual and neural distinction of the three types of SSU, with basic ecological SSU being supported by a limbic structure while sophisticated integrative or creative SSUs being developed in humans by multimodal association cortices.

The neural mechanism of controllability of posture and behavior in the bipedal humans for avoiding/protecting falling is highly important as one of the human survival strategies. There have been thus far few functional neuroimaging studies because of the restrictions placed on participants' movements. Here, we used functional magnetic resonanceimaging（fMRI） to investigate the neural mechanism underlying whole body instability, based on the action-observation and self-recognition paradigm. We performed fMRI measurements while 13 adult male subjects viewed video clips of their own and others, in the dynamically unstable, dynamically stable and statically stable conditions, respectively. As a results, the self-specific activity was observed only in the dynamically unstable condition ; the temporoparietaljunction, the parieto-insula vestibular cortex, the insular cortex and the anterior prefrontal cortex. This result showed that the neural substrate underlying self-recognition of one's own body instability consists of the vestibular, emotional, and adaptive systems.
