Journal ArticleDOI
Functional connectivity in the human language system: a cortico-cortical evoked potential study.
Riki Matsumoto,Dileep Nair,Eric LaPresto,Imad Najm,William Bingaman,Hiroshi Shibasaki,Hiroshi Shibasaki,Hans Lüders +7 more
TL;DR: The present study revealed a bidirectional connection between Broca's and Wernicke's areas probably through the arcuate fasciculus and/or the cortico-subcortico-cortical pathway, which suggests that perisylvian and extrasylVian language areas participate in the language system as components of a network by means of feed-forward and feed-back projections.
Journal ArticleDOI
Functional connectivity in human cortical motor system: a cortico-cortical evoked potential study.
Riki Matsumoto,Dileep Nair,Eric LaPresto,William Bingaman,Hiroshi Shibasaki,Hiroshi Shibasaki,Hans Lüders +6 more
TL;DR: The present study demonstrated a human motor cortico-cortical network connecting anatomically homologous areas of LMCx and MMCx along the rostrocaudal cognitive-motor gradient; and somatotopically Homologous regions in LMCX and M MCx in a reciprocal manner.
Journal ArticleDOI
Primary somatosensory cortex is actively involved in pain processing in human
Masutaro Kanda,Takashi Nagamine,Akio Ikeda,Shinji Ohara,Takeharu Kunieda,Naohito Fujiwara,Shogo Yazawa,Nobukatsu Sawamoto,Riki Matsumoto,Waro Taki,Hiroshi Shibasaki +10 more
TL;DR: It is postulated that the pain impulse is received in the crown of the postcentral gyrus in human.
Journal ArticleDOI
Increased synchronization of cortical oscillatory activities between human supplementary motor and primary sensorimotor areas during voluntary movements.
Shinji Ohara,Tatsuya Mima,Koichi Baba,Akio Ikeda,Takeharu Kunieda,Riki Matsumoto,Junichi Yamamoto,Masao Matsuhashi,Takashi Nagamine,Kenichi Hirasawa,Tomokatsu Hori,Tadahiro Mihara,Nobuo Hashimoto,Stephan Salenius,Hiroshi Shibasaki +14 more
TL;DR: This work investigated the electrocorticographic coherence between the supplementary motor and primary sensorimotor areas (SMA and S1–M1) by means of event-related partial coherence analysis in 11 intractable epilepsy patients and found premovement increase of coherence.
Journal ArticleDOI
Low-frequency electric cortical stimulation has an inhibitory effect on epileptic focus in mesial temporal lobe epilepsy
Junichi Yamamoto,Akio Ikeda,Takeshi Satow,Kazuhide Takeshita,Motohiro Takayama,Masao Matsuhashi,Riki Matsumoto,Shinji Ohara,Nobuhiro Mikuni,Jun Takahashi,Susumu Miyamoto,Waro Taki,Nobuo Hashimoto,John C. Rothwell,Hiroshi Shibasaki +14 more
TL;DR: The aim of this study was to investigate the effect of low‐frequency electric cortical stimulation on epileptic focus in humans and to establish an experimental protocol to investigate this effect.
