Abstract

Effect of acetylcholine (ACh) on presympathetic neurons of the rostral ventrolateral medulla (RVLM) was studied by extracellular recording technique and microiontophoresis in urethane-anaesthetized rats. The above finding suggests that presympathetic neurons of RVLM receive a tonic excitatory cholinergic input mediated by M receptors.
