Population PSTHs of multiwhisker responses during noradrenergic activation. A, Population PSTH (n = 5) of responses evoked by simultaneously stimulating six whiskers at 0.1 Hz, including the PW and five AWs (top row), and PSTHs consisting of the algebraic sum of the responses to each of these six whiskers stimulated alone (middle row) during control conditions and during application of norepinephrine in thalamus. The right column and bottom row overlay the PSTHs of responses shown in the vertically or horizontally aligned panels for comparison. B, Population PSTH (n = 5) of responses evoked by stimulating the PW alone (thin traces) or all six whiskers simultaneously, including the PW (thick traces). Different panels correspond to responses during control conditions and noradrenergic activation, during low-frequency (0.1 Hz) and high-frequency (10 Hz) whisker stimulation. C, Comparison of responses evoked by the PW and all six whiskers during the different conditions. Responses were measured by summing the spikes evoked during a 20 ms time window after the whisker stimulus (n.s., not significant).
