Cardiovascular effects of intra-amygdalar injection of AMPA. 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 AMPA into the basolateral amygdala. The 10 pmol and 30 pmol doses for both HR and MAP are significantly different from saline. AMPA (30 pmol),n = 6; all other doses, n = 4. HR: F(3,14) = 20.19; MAP:F(3,14) = 5.77.
