Extinction of cued fear memory involves a distinct form of depotentiation at cortical input synapses onto the lateral amygdala
The amygdala is known to be a critical storage site of conditioned fear memory. Among the two major pathways to the lateral amygdala (LA), the cortical pathway is known to display a presynapticExpand
