Effect of the GABAB receptor antagonist, CGP-35348, microinjected into the NTS on MAP and HR in the sham, 2K1C, 2K1C + EA, and 2K1C + SEA groups. (a) Representative original tracings showing AP and HR changes evoked by microinjection of CGP-35348 (100 pmol in 50 nL) into the NTS in the sham, 2K1C, 2K1C + EA, and 2K1C + SEA groups. The horizontal bar represents recording duration of 2 min. Arrows indicates the injection of CGP-35348 (CGP). The peak alteration (Δ) of MAP (b) and peak alteration (Δ) of HR (c) after microinjection of CGP-35348 (100 pmol in 50 nL) into the NTS of the sham, 2K1C, 2K1C + EA, and 2K1C + SEA groups. Values are means ± SE ( in each group). vs. sham group; vs. 2K1C group.
