Population data showing the effect of cholinergic and noradrenergic thalamic stimulation on FP sensory responses. A: FP responses, measured during a 5- to 30-ms window poststimulus, evoked during control and during cholinergic thalamic stimulation. 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) or single-whisker stimulation of the PW and of each of the 5 AWs (Aw1-Aw2). Inset marks with an asterisk the responses that showed a significant effect as determined with a pair-wise comparison. B: similar to A, but responses during cholinergic thalamic stimulation are compared with those during noradrenergic thalamic stimulation.
