Time evolution of the average relative gamma in the regions of interest. Both Group 1 and 2 are considered in the average. The response of the subjects in Group 2 was inverted before computing the average. RS1 and RS2 correspond to the central minute of the resting state blocks. MIST indicates the beginning of the stress session (3 min of training and 6 min of task). Relax indicates the beginning of the relaxing session (5 min). The shaded areas represent the standard error of the mean (SEM). (a) control group. (b) test group.
