Fear expression involves LTP in the following circuit: prelimbic area of the prefrontal(PL-PFC) cortex-> basal amygdala(BA) > central medial amygdala(Cem). True or false fear extinction involves LTD of that same circuit? O True False

Answer 1

1. Answer : False.

The main circuits that are involved are the sensory areas which processes the conditioned and unconditioned stimuli, certain regions of amygdala that undergo plasticity during learning, and the regions that bear an effect on the expression of specific conditioned responses. These pathways converge into the lateral amygdala. Long-term potentiation (LTP) and synaptic plasticity which enhances the response of lateral amygdala neurons to the conditioned stimulus occurs in lateral amygdala.

2. False

The above given statement is false.
