摘要
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 (CeA). Specifically, 1) long-term potentiation (LTP) at the BLA-CeA synapses was independent of inhibition and mediated through N-methyl-D-aspartate receptors (NMDARs) and L-type voltage-gated calcium channels (VGCCs), and 2) LTP in the LA-CeA pathway was gated by inhibition and mediated through VGCCs but not NMDARs.
