PSCH 343 Lecture Notes - Lecture 1: Anisomycin, Long-Term Memory, Papez Circuit
Document Summary
Structures that make up the papez circuit are hypothalamus, anterior thalamus, cingulate gyrus, and hippocampus. Amygdala is responsible for emotional processing in the brain (specifically fear- conditioning, which is a form of implicit memory). Fear-potentiated startle is a reaction from a presented stimulus, and is an indicator of a fear reaction. Lesions to amygdala do not usually block the unconditioned response to the aversive event (like a shock), indicating that the amygdala is not necessary to exhibit a fear response. However, amygdala lesions block the ability to acquire and express a conditioned response to the neutral conditioned stimulus that is paired with the aversive stimulus (pg. Memories may be vulnerable to disruption- both during encoding and reconsolidation/recall. If you interfere with protein synthesis you don"t consolidate the memory, you don"t form it . Need to look into this more for detailed answer- yes, i have partial notes, cause i couldn"t catch up with her explaining it so fast.
