Open AccessAssociation between enhanced carbonyl stress and decreased apparent axonal density in schizophrenia by multimodal white matter imaging
Carbonyl stress is a condition featuring increased rich reactive carbonyl compounds, which facilitate the formation of advanced glycation end products including pentosidine. We previously reported the relation...

The structural neural correlates of atypical facial expression recognition in autism spectrum disorder
Previous studies have demonstrated that individuals with autism spectrum disorder (ASD) are worse at recognizing facial expressions than are typically develo** (TD) individuals. The present study investigate...

Open AccessPhysical correlates of human-like softness elicit high tactile pleasantness
Touching an object can elicit affective sensations. Because these sensations are critical for social interaction, tactile preferences may be adapted to the characteristics of the human body. We have previously...

Open AccessAmygdala activity related to perceived social support
Perceived social support enhances well-being and prevents stress-related ill-being. A recent structural neuroimaging study reported that the amygdala volume is positively associated with perceived social suppo...

Open AccessNeural correlates of tactile simultaneity judgement: a functional magnetic resonance imaging study
Simultaneity judgement (SJ) is a temporal discrimination task in which the targets span an ultimately short time range (zero or not). Psychophysical studies suggest that SJ is adequate to probe the perceptual ...

Open AccessResting-state neural activity and connectivity associated with subjective happiness
The majority of people throughout the world rate subjective happiness as the top of the important thing in life. A recent structural neuroimaging study exploring neurocognitive mechanisms underlying subjective...

Open AccessAmygdala activation during unconscious visual processing of food
Hedonic or emotional responses to food have important positive and negative effects on human life. Behavioral studies have shown that hedonic responses to food images are elicited rapidly, even in the absence ...

Open AccessInhibition-excitation balance in the parietal cortex modulates volitional control for auditory and visual multistability
Perceptual organisation must select one interpretation from several alternatives to guide behaviour. Computational models suggest that this could be achieved through an interplay between inhibition and excitat...

Open AccessReconstructing the Neanderthal brain using computational anatomy
The present study attempted to reconstruct 3D brain shape of Neanderthals and early Homo sapiens based on computational neuroanatomy. We found that early Homo sapiens had relatively larger cerebellar hemispheres ...

Open AccessNeural correlates underlying change in state self-esteem
State self-esteem, the momentary feeling of self-worth, functions as a sociometer involved in maintenance of interpersonal relations. How others’ appraisal is subjectively interpreted to change state self-este...

Cerebellum: Anatomy, Physiology, Function, and Evolution
Until recently, few studies have focused on the evolution of the cerebellum in human lineage. While the major functional role of the cerebellum was traditionally thought to be fine motor control, recent neuroi...

Reconstruction and Statistical Evaluation of Fossil Brains Using Computational Neuroanatomy
To investigate differences in the cognitive abilities of fossil humans, it is important to be able to objectively infer possible differences in the anatomy and morphology of their brains from the insides of fo...

Putamen Volume is Negatively Correlated with the Ability to Recognize Fearful Facial Expressions
Findings of previous functional magnetic resonance imaging (MRI) and neuropsychological studies have suggested that specific aspects of the basal ganglia, particularly the putamen, are involved in the recognit...

Open AccessImpaired detection of happy facial expressions in autism
The detection of emotional facial expressions plays an indispensable role in social interaction. Psychological studies have shown that typically develo** (TD) individuals more rapidly detect emotional expres...

Open AccessBrain networks involved in tactile speed classification of moving dot patterns: the effects of speed and dot periodicity
Humans are able to judge the speed of an object’s motion by touch. Research has suggested that tactile judgment of speed is influenced by physical properties of the moving object, though the neural mechanisms ...

Open AccessRapid gamma oscillations in the inferior occipital gyrus in response to eyes
Eyes are an indispensable communication medium for human social interactions. Although previous neuroscientific evidence suggests the activation of the inferior occipital gyrus (IOG) during eye processing, the...

Open AccessIncreased frequency of social interaction is associated with enjoyment enhancement and reward system activation
Positive social interactions contribute to the sense that one’s life has meaning. Enjoyment of feelings associated through social interaction motivates humans to build social connections according to their per...

Open AccessDissociating the neural correlates of tactile temporal order and simultaneity judgements
Perceiving temporal relationships between sensory events is a key process for recognising dynamic environments. Temporal order judgement (TOJ) and simultaneity judgement (SJ) are used for probing this perceptu...

Open AccessSpatiotemporal neural network dynamics for the processing of dynamic facial expressions
The dynamic facial expressions of emotion automatically elicit multifaceted psychological activities; however, the temporal profiles and dynamic interaction patterns of brain activities remain unknown. We inve...
