Effect of cholinergic thalamic stimulation on intracellular multiwhisker responses. A and B: examples from 2 different cells showing the effect of cholinergic thalamic stimulation on intracellular potentials evoked by a 10-Hz multiwhisker stimulus train (10 stimuli at 10 Hz). Ten trials are overlaid per panel, except in the panel that overlays mean traces. Before averaging, the traces were filtered using a median filter to attenuate action potentials amplitudes. Bottom: simultaneously recorded FP responses. C: population data showing the effect of cholinergic thalamic stimulation on the slope of short-latency EPSPs evoked by low-frequency (1st stimulus in the 10-Hz train delivered at 0.1 Hz) and high-frequency (10th stimulus in the 10-Hz train) multiwhisker stimulation. D: population data showing the effect of cholinergic thalamic stimulation on short-latency EPSP trial-by-trial variability calculated by comparing the SD of the slope measurements from each cell in C (*P < 0.05).
