A Multiple Session Dataset of NIRS Recordings From Stroke Patients Controlling Brain–Computer Interface

We provide the experimental records, optodes placement data, online BCI performance, and a MATLAB code for simple analysis of hemodynamic response. Each filename includes subject ID, day and session number. The file contains a tabulated configuration of the channels (source–detector pairs in the 10–10 system), the raw light intensity data for each channel on both wavelengths, HbO and HbR concentrations in mmol/l, labels of mental tasks for each time point, and a confusion matrix of online classification.
