Facilitation of dendritic spikes in L6 neurons with backpropagating APs. a1, EPSC current injection just below and at threshold to the dendrite (383 μm from the soma) recorded at the dendrite (red trace, Vdend) and soma (black trace, Vsoma). a2, The subthreshold dendritic EPSP current injection 5 ms following a somatically evoked backpropagating AP produced a local dendritic spike. b, Average dendritic current threshold for a dendritic spike with the injection of dendritic current alone (left, no AP) and following a backpropagating AP (right, 5 ms). Asterisk indicates statistical significance (p = 0.017; n = 6).
