Noradrenergic modulation of the excitability of mPFC neurons. A, Representative traces of the effect of clonidine (100 μm) on the excitability of COM (Red) and CPn (green) neurons. B, Group data showing the increase in the number of spikes elicited in COM and CPn neurons before and after the addition of clonidine (Clon). C–F, Changes in spike parameters caused by clonidine in COM and CPn neurons. G, Changes in the interspike interval of both COM and CPn neurons. *p < 0.05 (significant difference between COM and CPN in control conditions); **p < 0.05 (significant difference between CPn control and CPn clonidine); triangle, p < 0.05 (significant difference between COM control and COM clonidine).
