最近的研究表明，使用植入电极记录的大脑活动直接解码和合成语音是可能的。虽然这种活动已经通过皮质表面灰质的皮层脑电(ECoG)记录进行了广泛的研究，但立体定向脑电(SEEG)提供了相对更广泛的覆盖面和进入更深层次的大脑结构，包括灰质和白质。本研究考察了脑-计算机接口中灰质和白质电极对语音活动检测的相对和联合作用。
Recent studies have shown it is possible to decode and synthesize speech directly using brain activity recorded from implanted electrodes. While this activity has been extensively examined using electrocorticographic (ECoG) recordings from cortical surface grey matter, stereotactic electroen-cephalography (sEEG) provides comparatively broader coverage and access to deeper brain structures including both grey and white matter. The present study examines the relative and joint contributions of grey and white matter electrodes for speech activity detection in a brain-computer interface.
