English: The spatio-temporal increases, back-propagation from areas 21 and 19, and subsequent decrease of d[ΔV(t)]/dt averaged over three animals. Statistically significant increases are shown yellow and red; statistically significant decreases are shown light blue and blue [p < 0.025 false discovery rate with correction for multiple comparisons (Materials and Methods)]. The cytoarchitectural borders are aligned (Methods) across animals. Notice also the net inhibition of the membrane potentials starting bilaterally in the periphery. The scale values shown in the scale bar for the d[ΔV(t)]/dt should be multiplied with 10−6.
