Journal ArticleDOI
Abnormal regional cerebral blood flow in childhood autism
Takashi Ohnishi,Hiroshi Matsuda,Toshiaki Hashimoto,Toshiyuki Kunihiro,Masami Nishikawa,Takeshi Uema,Masayuki Sasaki +6 more
TL;DR: The associations of impairments in communication and social interaction that are thought to be related to deficits in the theory of mind with altered perfusion in the medial prefrontal cortex and anterior cingulate gyrus and the obsessive desire for sameness are confirmed.
Journal ArticleDOI
Empathy and Judging Other's Pain: An fMRI Study of Alexithymia
Yoshiya Moriguchi,Jean Decety,Takashi Ohnishi,Motonari Maeda,Takeyuki Mori,Kiyotaka Nemoto,Hiroshi Matsuda,Gen Komaki +7 more
TL;DR: The hypofunction in the DLPFC, brain stem, cerebellum, and ACC and the lower pain-rating and empathy-related scores in ALEX are related to cognitive impairments, particularly executive and regulatory aspects, of emotional processing and support the importance of self-awareness in empathy.
Journal Article
Longitudinal evaluation of early Alzheimer's disease using brain perfusion SPECT.
Daiji Kogure,Hiroshi Matsuda,Takashi Ohnishi,Takashi Asada,Masatake Uno,Toshiyuki Kunihiro,Seigo Nakano,Masaru Takasaki +7 more
TL;DR: SPM analysis showed the characteristic early-AD rCBF pattern of selective decrease and longitudinal decline, which may be overlooked by a conventional region-of-interest technique with observer a priori choice and hypothesis, may closely relate to the pathophysiologic process of this disease.
Journal ArticleDOI
Impaired self-awareness and theory of mind: an fMRI study of mentalizing in alexithymia.
Yoshiya Moriguchi,Takashi Ohnishi,Richard D. Lane,Motonari Maeda,Takeyuki Mori,Kiyotaka Nemoto,Hiroshi Matsuda,Gen Komaki +7 more
TL;DR: The results suggest that alexithymic individuals have an impairment in mentalizing associated with an inability to take the perspective of others, and the skills involved in comprehending the self and others are inter-related and play an important role in emotion regulation.
Journal ArticleDOI
Functional Anatomy of Musical Perception in Musicians
Takashi Ohnishi,Hiroshi Matsuda,Takashi Asada,Makoto Aruga,Makiko Hirakata,Masami Nishikawa,Asako Katoh,Etsuko Imabayashi +7 more
TL;DR: It is suggested that activity in the auditory association areas and the prefrontal cortex of trained musicians is associated with absolute pitch ability and the use-dependent functional reorganization produced by the early commencement of long-term training.
