Cardiovascular effects of intra-amygdalar injection of bicuculline methiodide. Time course of changes in heart rate (HR; beats/min; top) and mean arterial pressure (MAP; mmHg; bottom) in conscious, chronically instrumented rats after bilateral injection of saline (250 nl/side) or various doses of bicuculline methiodide into the basolateral amygdala. The 30 pmol and 100 pmol doses for both HR and MAP are significantly different from saline. Each dose,n = 5. HR: F(3,16) = 66.23; MAP: F(3,16) = 34.99.
