Figure 11.

Examples of the effect of NE or 5HT on single-unit responses evoked by fictive whisking in four different cells (A–D). PSTHs are shown before and during application of NE (0.5 mm) or 5HT (0.5 mm) for two fictive whisking frequencies (0.5 and 5 Hz). Bottom, The difference (NE − Control or 5HT − Control) between the drug and the control period responses to denote the changes produced by the drug. Note that NE and 5HT typically suppress the evoked responses. The p values of the paired comparison test (Wilcoxon) are displayed.
