Amygdala central nucleus lesions attentuate acoustic startle stimulus-evoked heart rate changes in rats

Amygdala central nucleus lesions were used to test the hypothesis that stimulus-evoked heart rate can reflect the development of fear during acoustic startle testing. A 120-dB white noise startle stimulus produced freezing as well as phasic heart rate accelerations and decelerations, and an abrupt d...
