Chemical stimulation of the CeA evoked pressor and tachycardiac responses. a Sample traces for AP (top panel), MAP (middle panel) and HR (bottom panel) responses induced by three injections (arrows on the top and dotted lines) of the GABAA receptor antagonist bicuculline methiodide (2 mM, 0.5 μl) or saline (0.5 μl) control into the CeA. Scale bar on the right bottom indicates 10 min. b Group data showing the increase in MAP (upper panel) and HR (lower panel) in response to microinjection of saline (n = 5) or bicuculline methiodide (n = 5). *p < 0.05 saline vs. bicuculline methiodide (unpaired t test)
