Cardiovascular effects of acetylcholine microinjection into the ventrolateral and dorsal periaqueductal gray of rats

Abstract In the present study, we describe the cardiovascular effects of local acetylcholine (Ach) microinjection into both the ventrolateral (vlPAG) and dorsal (dPAG) periaqueductal gray areas of anesthetized rats and the possible local receptors involved with these responses. Microinjection of Ach...
