Abstract:
The prolactin (PRL) and corticosterone (CORT) responses to footshock stress were measured in rats after the first, fifth, and 57th exposure to the stress procedure. No reduction in the PRL or CORT responses was seen after repeated application of the footshock stress and the animals showed similar behavioral responses throughout. These results indicate that the hormonal and behavioral responses to footshock stress are not attenuated after an animal has been repeatedly exposed to the stress.
