abstract：:Synaptic plasticity in the amygdala is thought to underlie aversive or rewarding learning and emotional memories. In this study, different mechanisms were found to underlie synaptic plasticity in lateral (LA) and basolateral (BLA) amygdala pathways to the primary output nucleus of the amygdala, the central amygdala (C...
