Autor: Atsushi Kodabashi, Shinichiro Kamiya, Masaki Sekine, Toshiyo Tamura, Toshiaki Otsubo, Kouzou Takeuchi, Susumu Shimooki, Kazutaka Yatsushiro, Toshiro Fujimoto, Katsumi Nakamura, Eiichi Okumura

Publikováno v: The Open Neuroimaging Journal

We studied sex-related differences in gamma oscillation during an auditory oddball task, using magnetoencephalography and electroencephalography assessment of imaginary coherence (IC). We obtained a statistical source map of event-related desynchroni

Estimation Method on Multiple Sources of MEG Based on the Columnar Structure of the Cerebral Cortex

Autor: T. Fujimoto, Atsushi Kodabashi, Hiroshi Fukuda, Masato Odagaki, Osamu Hiwaki

Publikováno v: IEEE Transactions on Magnetics. 44:4425-4431

An estimation method for multiple sources of magnetoencephalogram is proposed. In the proposed method, the assumed dipoles are arranged on and oriented perpendicular to the surface of the cerebral cortex based on the hypothesis of the functional colu

Modification of Motor Evoked Potentials Caused by Electrical Peripheral Nerve Stimulation in Transcranial Magnetic Stimulation

Autor: Atsushi Kodabashi, Masato Odagaki, Hiroshi Fukuda, Osamu Hiwaki, T. Fujimoto

Publikováno v: IEEE Transactions on Magnetics. 44:4440-4443

Somatosensory cortex receives afferent inputs from skeletal muscles and joints while a voluntary movement is conducted. Although this sensory feedback may regulate the efferent motor control signals generated in the motor cortex, the relationship bet

Determination of hemispheric language dominance using functional magnetic resonance imaging and the Shiritori (Japanese word chain) task in patients with epilepsy: Comparison with the Wada test

Autor: Koji Iida, Toshiaki Otsubo, Kazunori Arita, Hiroshi Tokimura, Hiroshi Hosoyama, Sei Sugata, Ryosuke Hanaya, Katsumi Nakamura, Atsushi Kodabashi, Toshiro Fujimoto, Yumi Kashida, Noriko Tsumagari

Publikováno v: Epilepsy research. 124

Purpose The Wada test has been the gold standard for determining hemispheric language dominance (HLD) in the presurgical evaluation of patients scheduled for neurosurgical procedures. As it poses inherent risks associated with intra-arterial catheter

Temporal activities during P3 components on the working memory-related brain regions: N-back ERP study

Autor: Toshiyo Tamura, Toshiro Fujimoto, Atsushi Kodabashi, Masaru Yarita, Yoshiaki Nakao

Publikováno v: BHI

In recent cognitive neuroscience, many studies have been conducted on the human working memory. However, the temporal activities in the working memory-related brain regions are not clear yet. To elucidate the temporal activities of the working memory
