a Schematic representation of multichannel near-infrared spectroscopy (NIRS) probes. The NIRS probes were placed over the frontal surface of the head. b An anatomical brain region [Brodmann area (BA)] for the channels’ coordinates were probabilistically estimated by using a MRIcro. A probabilistic mapping of the 22 channels and its corresponding anatomical brain region are summarized
