Responses to microinjection of GABA at the beginning of the each protocol are shown. Significant increases in both arterial pressure (MAP) and renal sympathetic nerve activity (RSNA) were observed following injection of GABA in the CVLM. Microinjection of GABA in the RVLM produced significant decreases in MAP and RSNA. Rats in Protocols 1 and 2 had prior right NTS lesions and responses shown are to left side injections. The averaged data for left and right side injections is shown for Protocol 3. Values = mean ± SEM;
