摘要：

Brain computer interface (BCI) techniques have been remarkably developed in the last decades. Recently, researchers have investigated the sensorimotor integrated bi-directional BCI using micro-recordings. However, this approach has suffered from the insufficient coverage of cortical surface leading to the limited applicability. In this study, we focus on several macroscopic aspects to overcome the limitation by direct cortical stimulation (DCS) and ECoG-based movement decoding. We found that cortical areas elicited somatosensation by DCS are wide spread beyond the S1. In addition, we showed that movement imagery is successfully decoded by multi-regional neural population activities beyond the primary areas.
