Significant responses. Left, percentage of cells of the total recorded (M1, 34 V4 cells and 102 dlPFC cells; M2, 104 V4 cells and 46 dlPFC cells) that exhibited a significant change in firing rate from baseline (intertrial period) during social events, averaged across sessions and monkeys. For each cell, P < 0.01, Wilcoxon signed-rank test with FDR correction. Right, percentage of neurons of the total recorded that responded only to choice (self and/or partner), only to fixations (reward and/or partner), both fixations and choice (mixed) or none at all (other). * P < 0.05, ** P < 0.01, *** P < 0.001.
