TL;DR: The findings suggest the possibility of aberrant laterality in neural pathways and connectivity patterns related to the pallidum in schizophrenia, and replicate the rank order of effect sizes for subcortical volumetric changes in schizophrenia reported by the ENIGMA consortium.
Journal ArticleDOI

TL;DR: It is found that schizophrenia, bipolar disorder, and autism spectrum disorder share similar white matter microstructural differences in the body of the corpus callosum; schizophrenia and bipolar disorder featured comparable changes in the limbic system, such as the fornix and cingulum.
Journal ArticleDOI
Role of subcortical structures on cognitive and social function in schizophrenia.
Daisuke Koshiyama,Masaki Fukunaga,Naohiro Okada,Fumio Yamashita,Hidenaga Yamamori,Yuka Yasuda,Michiko Fujimoto,Kazutaka Ohi,Haruo Fujino,Yoshiyuki Watanabe,Kiyoto Kasai,Ryota Hashimoto +11 more
TL;DR: The results from this large-scale investigation shed light upon the role of specific subcortical nuclei on cognitive and social functioning in schizophrenia.
Journal ArticleDOI
Gamma-Band Auditory Steady-State Response as a Neurophysiological Marker for Excitation and Inhibition Balance: A Review for Understanding Schizophrenia and Other Neuropsychiatric Disorders
Mariko Tada,Kenji Kirihara,Daisuke Koshiyama,Mao Fujioka,Kaori Usui,Takanori Uka,Misako Komatsu,Naoto Kunii,Tsuyoshi Araki,Kiyoto Kasai +9 more
TL;DR: Recent ASSR studies in patients with schizophrenia and other neuropsychiatric disorders are reviewed and it is shown that synaptic interactions between parvalbumin-positive GABAergic interneurons and pyramidal neurons contribute to the regulation of E/I balance, which is related to the generation of gamma oscillation.
Journal ArticleDOI
Electrophysiological evidence for abnormal glutamate-GABA association following psychosis onset.
Daisuke Koshiyama,Kenji Kirihara,Mariko Tada,Tatsuya Nagai,Tatsuya Nagai,Mao Fujioka,Eriko Ichikawa,Kazusa Ohta,Motoko Tani,Maiko Tsuchiya,Akiko Kanehara,Kentaro Morita,Kingo Sawada,Jun Matsuoka,Yoshihiro Satomura,Shinsuke Koike,Motomu Suga,Tsuyoshi Araki,Kiyoto Kasai +18 more
TL;DR: These findings provide the first in vivo evidence that an abnormal association of the electrophysiological indices of NMDAR and GABA dysfunctions may be present in recent-onset schizophrenia.
