FIG. 10.

Population data showing the effect of Pr5 plus thalamic disinhibition on barrel cortex single-unit and FP responses. A: single-unit barrel cortex responses, measured during a 5- to 15-ms window poststimulus, evoked during control (black symbols) and during Pr5 plus thalamic disinhibition (BC; gray symbols). The x axis shows the responses evoked by each of the 10 stimuli in the 10-Hz train. Each block of 10 stimuli correspond (left to right) to multiwhisker stimulation delivered simultaneously to all 6 whiskers (ALL), single-whisker stimulation of the PW and of each of the 5 AWs (Aw1–Aw5). Inset: asterisk marks the responses that showed a significant effect of disinhibition as determined with a pair-wise comparison. B: the graph is organized as in A but shows the negative peak FP amplitude for barrel cortex responses measured during a 5- to 30-ms window poststimulus.
