Figure 6

Paired-pulse medial lemniscal stimulation. (a) LFP was larger during whisking (P < 0.0005, Mann-Whitney test; whisking, n = 207 stimuli; nonwhisking, n = 417). Paired-pulse suppression (25-ms interval) was less robust during whisking. Note that the late response to the second pulse was barely detectable during nonwhisking (dashed ellipse). (b) PSTHs of simultaneously recorded MUA (0.1-ms bins). Spike counts were larger during whisking in response to the second stimulus, and there was less paired-pulse suppression. Data are presented as in Figure 4b.(c) Adaptation of thalamic responses to paired-pulse medial lemniscus stimulation during whisking and nonwhisking periods. Paired-pulse adaptation indices for seven recording sessions are calculated as the ratio of MUA spikes counts evoked by the second pulse to those evoked by the first pulse. The gray line indicates the unity line.
