“L” represents the left side; “R” represents the right side. VRMS, virtual reality music stimulation; VRAO, virtual reality action observation; VRMI, virtual reality motor imagination; HBT, total hemoglobin; ROIs, brain regions of interest; FDR, false discovery rate; FC, functional connectivity; Only one brain channel in brain regions LM1 and RM1 is not discussed.
