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...

description 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 decrease in tonic heart rate, in sham-operated rats.
