Figure 8. Prevention of the inhibition of baroreflex bradycardia inhibition produced by pharmacological activation of the CnF following microinjection of muscimol into the dorsolateral PAG.

Representative recordings showing that the baroreflex cardiac response inhibition normally occurring during CnF activation (compare Control 1 and Experimental 1 in A, n = 5) was reversed by microinjection of muscimol into the dlPAG (B). Each group is the mean ± SEM. *P < 0.005.
