Acute experiments in cats revealed effects of GABA injections (2.10(-5)-5.10(-5) M/l) into the neuronal structures of the dorso-medial medulla after M-cholinoreceptors had been blocked. Hypotensive action of GABA injected into the n. ambiguous and ventral reticular nucleus was shown to be actualized through participation of bulbar M-cholinoreceptors. Effects of GABA injected into n. tractus solitarius occurred with no consistent participation of the central M-cholinoreceptors.
