The effectiveness of epidural ECoG on brain computer interface in primate

초록

Recently, several studies have reported use of epidural electrocorticography (eECoG) for brain computer interface (BCI). However the feasibility and performance of eECoG on BCI were not fully evaluated yet. In this study, we aimed to verify the usability of implanted eECoG on BCI in primate. Two micro electrode patches were inserted over duramater on rhesus monkey. The monkey performed four directional eye movement tasks responding to target's color change. As results, eECoG showed the different activation pattern between before and after the perception of the color change and target direction. This demonstrates the possibility of BCI using eECoG.
