Sensory gating is cortex-dependent. a Representative example showing contact-evoked responses during non-whisking (dark red) and whisking (light red) epochs in a Pr5 neuron recorded in an animal with somatosensory cortex lesions. All conventions as in Fig. 2a. b Population PSTHs of all Pr5 units recorded from lesioned animals shown normalized to baseline firing rates as in Fig. 2b. c Scatterplot identical to that shown in Fig. 2c (blue), but now with the data from Pr5 neurons in lesioned animals plotted on top (red). d Comparison of peak widths of evoked responses in all Pr5 units in lesioned (red) and intact (blue) animals. Effect sizes (area under ROC curve; AUC) were calculated considering distributions of firing rates obtained for each post-stimulus bin vs. the mean pre-contact baseline (n = 53, lesioned; n = 23, intact). Bins that were significantly different (p < 0.05; Wilcoxon rank sum test) from baseline are indicated by a green dot
