Whisking reduces evoked local field potential (LFP) activity during the inhibitory period but not during the excitatory period. (A) Example of LFP response, which demonstrates sharp negative deflection (a) followed by long positive wave (b), presumably corresponding to electrically evoked excitation and inhibition respectively (cf. Figure 1D). (B) Peak amplitudes of excitatory LFP response (a) to both active and passive contacts yielded no difference, unlike amplitude of the inhibitory period (b), which had higher maximum amplitude during passive contacts in all three animals (**significant using Mann-Whitney U-test, error bars CI95, see text). (C) Mean LFP responses to both passive (green) and active (orange) contacts in all three animals (the infraorbital nerve was cut in the animal shown on top).
