Supplemental Figure 1. Representative activity of a VPM cell during quiescent and activated states caused by RF stimulation.
A. Spontaneous activity of the cell measured during a 1 sec time window in the absence of whisker stimulation during quiescent and activated states. During RF stimulation trials, this window corresponds to the period between the offset of the RF stimulation and the onset of the whisker stimulation. During control (quiescent) trials, this period corresponds to 1 sec before the whisker stimulus.
B. PSTHs showing responses to stimulation of the PW (C6) and six AWs (C7-E5) during quiescent and activated states. Whisker stimulation was delivered at 0.1 and 10 Hz. The two left columns show individual PSTHs of the responses to stimulation at 0.1 Hz during quiescent (black fill) and activated states (gray fill). The two right columns overlay PSTHs of responses during quiescent (black fill) and activated states (gray traces) for 0.1 and 10 Hz whisker stimulation.

Supplemental Figure 2. Representative activity of a putative tail-region VPM cell during thalamic activation caused by application of carbachol in VPM and reversibility by atropine.
A and B. PSTHs showing responses to low frequency (0.1 Hz; A) and high frequency (10 Hz, B) stimulation of the PW (D1) and five AWs (E2-γ) during quiescent and activated states caused by carbachol, and reversibility of the effects of carbachol by atropine. Also shown is the response to simultaneous stimulation of the six whiskers (lower row). In the lower row, we overlay the algebraic sum of the responses to individual stimulation of the six whiskers (light gray trace) for comparison with the simultaneous stimulation.
