Group averaged ΔHbR time courses for all channels and all three conditions: Labels on top indicate the channel number (e.g. Ch-1) and the overall number of subjects averaged in each condition of the corresponding channel. All subplots are scaled as shown in the enlarged channel 10 (insert right), which showed a significant HbR decrease 8–20 s after hand gripping onset in all three conditions. In the insert, the SEM is indicated in shaded colors. Yellow bars represent the hand gripping period.
