Abstract:
Cycloheximide application on the cerebellar vermis 5 min after learning impairs consolidation of long-term extinction of the defense component of the acoustic startle response. Application 2 hours after training inhibits consolidation of extinction of orientation and exploratory components of the acoustic startle response and long-term fear memory in the experimental chamber before the start of acoustic stimulation. These findings indicate that the cerebellar vermis is selectively involved in long-term memory formation in certain types of defense behavior at different time after training.
