Summary
This proposal build on the establishment by our laboratory of the assay capable of detecting free fatty acids, with great accuracy and sensitivity. Using this assay we have uncovered a completely new pathway highlighting the production of saturated free fatty acids linked to learning and memory. We will fully define how this pathway is regulated in the brain.
Fear Relapse: Neural Substrates Underlying Its Inhibition And Prevention

Summary
Exposure-based therapies are effective for anxiety disorders such as post traumatic stress, but two challenges remain: 1) patients that have learned to inhibit their fear are likely to relapse, requiring further therapy; 2) many drop out of therapy since it is aversive and anxiety provoking. We use an animal model to: 1) identify the neural substrates underlying fear inhibition; and 2) determine the conditions that prevent relapse and encourage participation in treatment.
The Effect Of Oxytocin On The Formation, Expression And Inhibition Of Fear Memories

Summary
Oxytocin is a hormone peptide which reduces amygdala activation to threatening stimuli and reduces anxiety in people and laboratory rodents. These results suggest that oxytocin could be a valuable pharmacological adjunct to exposure-based therapy for anxiety disorders. However, several questions must be answered before its therapeutic potential can be determined. As such, this project examines the effects of oxytocin on fear-related behaviours in rats, and neural fear circuits in the amygdala.
