Long-lasting S1 and S2 cortical effects on Pr5 neurons in matching conditions. (A) histograms show PSTHs in control condition, 1 min and 5 min after stimulation train in a representative Pr5 neuron. (B) plot of the mean tactile responses in control condition and after S1 (blue diamonds) or S2 (red squares) cortical electrical stimulation (3 trains of stimuli; 50 Hz during 500 ms repeated each 2 s) in Pr5 neurons recorded in the matched condition. Pr5 neurons increased their tactile response after a stimulation train in the S1 cortex (n = 21). A similar stimulation train in the S2 cortex did not modify tactile responses in Pr5 neurons (n = 12). * P < 0.05, ** P < 0.01 statistical significance after cortical stimulation train with respect to control values.
