Visual fixation is an item of the Coma Recovery Scale-Revised (CRS-R), it is difficult to be detected by clinicians using the behavioral scales because of fluctuations of arousal level and the presence of motor impairment in disorders of consciousness (DOC) patients. Brain-computer interfaces (BCIs), which directly detect brain response without any behavioral expression, can be used to evaluate a...
The requirements of exploring multi-site responsive stimulation for epilepsy treatment have driven the development of neurostimulator with more recording channels, more stimulation channels, and more powerful on-board calculation. In this paper, a multi-channel closed-loop stimulation system based on FPGA platform, which implements 32-channel 30kS/s recording and 4-channel arbitrary waveform (up to...
The aim of this study is to determine the potential prognostic value of using Brain-computer Interface (BCI) to identify patients with disorder of consciousness (DOC), who show potential for recovery. A retrospective study involved 51 patients with DOC were conducted. Each patient conducted in a BCI experiment to detect awareness and received a 3-months follow-up. The BCI accuracies were correlated...
