Figure 2. Example of a barosensitive type II MnPO-PVN neurone.

Figure 2

A, ICA injection of Ang II significantly increased MnPO-PVN unit discharge whereas isotonic saline had no effect. B, ICA injection of hypertonic NaCl did not alter cell discharge; however, baroreceptor activation produced by PE significantly increased ABP but decreased cell discharge. C, this MnPO-PVN neurone was antidromically activated from the right PVN (a, latency: 12 ms; threshold, 260 μA). The antidromic spike was collided with a spontaneous action potential (b). ▴, spontaneous action potential; *, stimulus artifact.
