Figure 3. Effect of thalamic activation induced by RF stimulation on whisker-evoked responses in VPM neurons.

Figure 3

A, RF stimulation (100 Hz, 1 s) induces thalamic activation which was monitored by field potential (above) and single-unit recordings (below) using the same electrode placed in the VPM thalamus. B, the effect of four whisker stimuli (1 ms pulses) delivered at 20 Hz and at 2 Hz is shown as a raw trace for one trial (above) and as the binned sum of 14 trials (below). C, the response to the same whisker stimulation as in B is displayed during thalamic activation induced by RF stimulation. The 1 ms positive square pulses on the raw traces mark the time of the sensory stimulus. Notice that the x-axis for the 2 Hz stimulation is not continuous.
