We performed fMRI measurements in normal children to clarify which cortical areas are commonly involved in the mirror system (MS) and mentalizing, which areas are specific for mentalizing, and whether children have the same neural networks for MS and mentalizing as adults. Normal children had the same neural networks for the MS and mentalizing as adults.(More)
Understanding the neural mechanisms underlying speech production has a number of potential practical applications. Speech production involves multiple feedback loops. An audio-vocal monitoring system plays an important role in speech production, based on auditory feedback about the speaker's own voice. Here we investigated the mu-rhythm activity associated(More)
We report the enhanced expression of early forms of microtubule-associated proteins (MAPs) in cortical dysplasia in surgical resections from 17 children with intractable epilepsy. Large neurons, which represent one of the characteristic cellular features of cortical dysplasia, showed strong immunoreactivity for MAP1B, as well as the low-molecular-weight(More)
It is assumed that children with autism spectrum disorders (ASD) have specificities for self-face recognition, which is known to be a basic cognitive ability for social development. In the present study, we investigated neurological substrates and potentially influential factors for self-face recognition of ASD patients using near-infrared spectroscopy(More)
The current study examined the hemodynamic response during the Go/NoGo task in children with/without attention deficit/hyperactivity disorder (ADHD). Using near-infrared spectroscopy, oxy-Hb and deoxy-Hb concentration changes in the frontal areas were compared during the conditions with/without inhibitory demand. Compared with typically developing children,(More)
Since the first report by Brenner et al. of mutations in the glial fibrillary acidic protein (GFAP) gene in patients with Alexander disease, several molecular genetic studies have been performed in different ethnic groups. We previously reported a Japanese patient with a mutation, R239C, which is identical to one commonly found in American patients. Here we(More)
This study aimed at investigating the effect of distraction on working memory and its underlying neural mechanisms in children with attention-deficit/hyperactivity disorder (ADHD). To this end, we studied hemodynamic activity in the prefrontal cortex using near-infrared spectroscopy while 16 children with ADHD and 10 typically developing (TD) children(More)
We reported a learning-disabled child who demonstrated a specific disorder of Kanji writing. A right-handed 13-year-old boy had showed no abnormality in general intelligence (VIQ114 and PIQ 100 in WISC-R), but could write only 35% of Kanji, which he should have learned six years before. It was necessary to develop a new test battery to detect the symptom(More)
Bronx Waltzer (bv) mouse, which has been used as a model of hearing and vestibular dysfunction, shows remarkable repetitive circling behavior. This study investigated whether the behavior is caused by the asymmetry of striatal function by observing the behavior of the bv mice following microinjection of dopamine D1 agonist, A68930 into the striatum(More)
