Effects of intracerebroventricularly administered cholecystokinin antisera on active avoidance and conditioned
Acta Physiologica Academiae Scientiarum Hungaricae
|January 1, 1982
Abstract:
The effects of intracerebroventricular administration of two different cholecystokinin antisera were tested on acquisition and extinction of active avoidance behaviour as well as on acquisition, maintenance and extinction of conditioned feeding behaviour of rats. Both antisera delayed the extinction of active avoidance and conditioned feeding response, while they were ineffective on acquisition and maintenance. These data suggest that the endogenous CCK of the brain might be a physiological modulator of extinction processes.
