It has been proposed that motor imagery contains an element of sensory experiences (kinesthetic sensations), which is a substitute for the feedback would normally arise from overt action. No evidence provided about whether kinesthetic sensation centrally simulated during imagery. We psychophysically tested palmar flexion or dorsiflexion right wrist influence illusory elicited by tendon vibration. also movement shared same neural substrates involving peripheral stimuli. Regional cerebral...
To investigate the hypothesis that early visual processing of stimuli might be boosted by signals emotionality, we analyzed event related potentials (ERPs) twelve right-handed normal subjects. Gray-scale still images faces with emotional (fearful and happy) or neutral expressions were presented randomly while subjects performed gender discrimination faces. The results demonstrated emotion (both fear happiness) elicited a larger negative peak at about 270 ms (N270) over posterior temporal...
Impairment of social interaction via facial expressions represents a core clinical feature autism spectrum disorders (ASD). However, the neural correlates this dysfunction remain unidentified. Because is manifested in real-life situations, we hypothesized that observation dynamic, compared with static, would reveal abnormal brain functioning individuals ASD. We presented dynamic and static fear happiness to high-functioning ASD age- sex-matched typically developing controls recorded their...
The present study attempted to reconstruct 3D brain shape of Neanderthals and early Homo sapiens based on computational neuroanatomy. We found that had relatively larger cerebellar hemispheres but a smaller occipital region in the cerebrum than long before time disappeared. Further, using behavioural structural imaging data living humans, abilities such as cognitive flexibility, attention, language processing, episodic working memory capacity were positively correlated with size-adjusted...
Background The relationships between facial mimicry and subsequent psychological processes remain unclear. We hypothesized that the congruent muscle activity would elicit emotional experiences experienced emotion induce recognition. Methodology/Principal Findings To test this hypothesis, we re-analyzed data collected in two previous studies. recorded electromyography (EMG) from corrugator supercilii zygomatic major obtained ratings on scales of valence arousal for emotions (Study 1)...
Happiness is a subjective experience that an ultimate goal for humans. Psychological studies have shown happiness can be measured reliably and consists of emotional cognitive components. However, the neural substrates remain unclear. To investigate this issue, we used structural magnetic resonance imaging questionnaires assessed happiness, intensity positive negative experiences, purpose in life. We found relationship between score gray matter volume right precuneus. Moreover, same region...
Abstract Individuals can experience negative emotions (e.g., embarrassment) accompanying self-evaluation immediately after recognizing their own facial image, especially if it deviates strongly from mental representation of ideals or standards. The aim this study was to identify the cortical regions involved in self-recognition and along with self-conscious emotions. To increase range self-evaluation, we used feedback images chosen a video recording, some which deviated significantly normal...

An exploration of the physiological correlates subjective emotional states has theoretical and practical significance. Previous studies have reported that valence arousal correspond to facial electromyography (EMG) electrodermal activity (EDA), respectively, across stimuli. However, results were inconsistent, no study investigated subjective–physiological concordance time, measures remain controversial. To investigate these issues, while healthy adults (n = 20) viewed films, we assessed...
Sign language activates the auditory cortex of deaf subjects, which is evidence cross-modal plasticity. Lip-reading (visual phonetics), involves audio-visual integration, hearing subjects. To test whether plasticity occurs within areas involved in we used functional MRI to study seven prelingual signers, 10 non-signers and nine signers. The visually presented tasks included mouth-movement matching, random-dot motion matching sign-related matching. conditions with or without visual phonetics,...
Humans can judge grating orientation by touch. Previous studies indicate that the extrastriate cortex is involved in tactile judgments, suggesting this area related to visual imagery. However, it has been unclear which neural mechanisms are crucial for processing of orientation, because imagery not always required spatial tasks. We expect such involve multisensory areas, our perception space highly integrated across modalities. The current study uses functional magnetic resonance imaging...
Abstract Humans can recognize common objects by touch extremely well whenever vision is unavailable. Despite its importance to a thorough understanding of human object recognition, the neuroscientific study this topic has been relatively neglected. To date, few published studies have addressed haptic recognition nonbiological objects. We now focus on body, particularly salient category for touch. Neuroimaging demonstrate that regions occipito-temporal cortex are specialized visual perception...
Face perception is critical for social communication. Given its fundamental importance in the course of evolution, innate neural mechanisms can anticipate computations necessary representing faces. However, effect visual deprivation on formation that underlie face largely unknown. We previously showed sighted individuals recognize basic facial expressions by haptics surprisingly well. Moreover, inferior frontal gyrus and posterior superior temporal sulcus subjects are involved haptic...
Autism spectrum disorder (ASD) is a neurodevelopmental characterized by behavioral impairment in social interactions. Although theoretical and empirical evidence suggests that the brain network could be neural underpinnings of ASD, previous structural magnetic resonance imaging (MRI) studies adults with ASD have not provided clear support for this, possibly due to confounding factors, such as language impairments. To further explore this issue, we acquired MRI data analyzed gray matter...
Abstract Positive social interactions contribute to the sense that one’s life has meaning. Enjoyment of feelings associated through interaction motivates humans build connections according their personal preferences. Therefore, we hypothesized itself activates reward system in a manner depends upon individual To test this hypothesis, conducted functional magnetic resonance imaging (fMRI) study which 38 participants played virtual ball-toss game number ball tosses participant was either...
We evaluated the neural substrates of cross-modal binding and divided attention during audio-visual speech integration using functional magnetic resonance imaging. The subjects (n = 17) were exposed to phonemically concordant or discordant auditory visual stimuli. Three different matching tasks performed: auditory–auditory (AA), visual–visual (VV) auditory–visual (AV). Subjects asked whether prompted pair congruent not. defined for within-modal by VV–AA AA–VV. area as intersection loci AV–AA...
