Fishers exact test compares the proportions of cells responsive to communication calls in each cortical area with the proportions that responded to simple stimuli (*more responsive to calls at the p<0.05 level, **more responsive to calls at the p<0.001 level, # less responsive to calls at the p<0.05 level, ## less responsive to calls at the p<0.001 level).
