Responses of Individual Neurons during Steady State in the POm, VPMvl, and VPMdm
Examples of responses of individual neurons during steady state are shown for the POm (A), VPMvl (B), and VPMdm (C) and (D) to whisking in air (black) and whisking against an object (red), relative to the time of protraction onset (t = 0). For each cell, the top graph depicts a raster display of single spikes accumulated from three randomly selected cycles from cycles 5–10. Middle graphs depict the PSTH computed for the entire steady-state period (cycles 5–10). Bottom graphs depict the horizontal angle of the principal whisker during a single cycle; ordinate denotes whisker angle, full scale = 50°, and traces were low-pass filtered at 160 Hz. Contact times, during touch trials, are indicated by arrows.
