(A) PC complex-like-spikes (Cp-like-Ss; bottom) evoked by somatic current injection with fast kinetics (top traces; black; Ifast; 0.4 ms rise and 4 ms decay), fast kinetics with 80% charge of Ifast (green; Ifast -20%Q), and slow kinetics with 80% charge of Ifast (red; Islow-20%Q; 0.4 ms rise and 5 ms decay).
(B) Summary data shows a reduction in the total number of spikelets as a result of Islow-20%Q (red) current injection but not Ifast-20%Q (green) compared to Ifast (open circles; p < 0.05). Each data point represents individual experiments and black horizontal traces are the mean values ± SEM.
(C – E) Summary of spikelet height (C), maximal rate of spikelet rise (D), and ISI (E) of the first three spikelets within CpS evoked with Ifast (open circles), Ifast-20%Q (green), and Islow-20%Q (red) current injection.
