Ushiba教授の研究室では、脳-コンピュータインターフェース（BCI）を用いた脳卒中後の運動機能回復のメカニズムを解明しています。特に、視覚的・皮膚感覚的フィードバックの有効性や、運動関連脳波（SMR）の変動と脳領域活動の関連を、EEGとfMRIを併用して解析しています。慢性期の重度麻痺患者を対象とした臨床的・神経生理学的アプローチにより、神経可塑性の向上に寄与するフィードバック設計の最適化を目指しています。

Recent studies have shown that scalp electroencephalogram (EEG) based brain-computer interface (BCI) has a great potential for motor rehabilitation in stroke patients with severe hemiplegia. However, key elements in BCI architecture for functional recovery has yet to be clear. We in this study focused on the type of feedback to the patients, which is given contingently to their motor-related EEG in a BCI context. The efficacy of visual and somatosensory feedbacks was compared by a two-group stud
Blockade of the scalp electroencephalographic (EEG) sensorimotor rhythm (SMR) is a well-known phenomenon following attempted or executed motor functions. Such a frequency-specific power attenuation of the SMR occurs in the alpha and beta frequency bands and is spatially registered at primary somatosensory and motor cortices. Here, we hypothesized that resting-state fluctuations of the SMR in the alpha and beta frequency bands also covary with resting-state sensorimotor cortical activity, without
