Results of oxyhemoglobin (HbO) and total hemoglobin (HbT) values during bilateral arm raising movements in healthy participants.

(A) Five regions of interest based on the Brodmann area (BA) and anatomical location of areas of the brain. The primary sensorimotor cortex (SM1): BA1, 2, 3, and 4; supplementary motor area (SMA); premotor cortex (PMC); prefrontal cortex (PFC): BA8 and 9; posterior parietal cortex (PPC): BA5 and 7; the arm somatotopic area of the SM1 (medial boundary: medial margin of the precentral knob, lateral boundary: lateral margin of the precentral knob); the leg somatotopic area of the SM1 (medial boundary: longitudinal fissure, lateral boundary: medial margin of the precentral knob). (B) Group-average t-statistic maps of HbO and HbT during performance of bilateral arm raising movements using NIRS-SPM software (corrected with expected Euler characteristics, P < 0.05).
