Specifically, two-factor analysis of variance (ANOVA) for ChR2 data demonstrated highly significant effects of stimulation (F(1,60) = 7.467, p < 0.01) and distance (F(4,60) = 11.043, p < 0.001); post hoc testing indicated significant effects of ChR2 stimulation on coherence between electrodes at 200 ( p = 0.003) and 280 μm ( p = 0.026) distances ( Fig. 4 D ).
