Activated brain regions for one representative subject over different sessions (A) within the same day and (B) across subsequent days. A channel was classified as activated for a p < 0.05 for both HbO and HbR with the additional constrain that the coefficient associated with HbO and HbR needed to be positive and negative, respectively. In addition to the activated brain regions in each session, the values of heart rate (HR) and mean arterial blood pressure (MAP) acquired immediately before and after the fNIRS measurements are shown.
