Fig.5 Averaging waveforms unpleasant emotional stimulus presentation at ch 15 In the case of the unpleasant emotional stimulus, a significant increase in concentration of oxy-Hb unpleasant emotional stimulus, significantly increase of oxy-Hb concentration was found in the periphery of 	./cache/work_baa42pags5bzhey4donm65vfce.pdf	./txt/work_baa42pags5bzhey4donm65vfce.txt
