Functional near-infrared spectroscopy system used to collect relative changes in oxyhemoglobin and deoxyhemoglobin concentrations. A The data acquisition and sensor used. The sensor allowed for measurement of cerebral and extracerebral activities using long (2.5 cm) and short (1 cm) source detector separation (SDS) channels. B The location of sources or light emitting diodes (red circles), detectors or photodiodes (yellow circles), and channels (white circles) on the prefrontal cortex. Channels 1 through 16 represent cerebral measurements, while channels 17 and 18 represent extracerebral measurements
