巴甫洛夫恐惧条件反射依赖于杏仁核神经元的突触可塑性。在这里,我们回顾最近的电生理,分子和行为的证据表明存在一个分布式的神经回路调节杏仁核突触可塑性在恐惧学习。这种涉及中脑导水管周围灰质(PAG)区域的投射的电路可以与关联和计算学习模型所描述的恐惧学习的预测误差和期望调制相关联。它控制着恐惧学习是否发生,以及发生多少,当它们是意料之外的时候,它通过发出厌恶事件的信号来控制。功能性神经影像学和临床研究表明,这种预测回路在人类恐惧学习过程中被招募,并有助于临床焦虑症的治疗。这种令人厌恶的预测误差回路可能代表了哺乳动物调节恐惧学习的保守机制。
Pavlovian fear conditioning depends on synaptic plasticity at amygdala neurons. Here we review recent electrophysiological, molecular, and behavioral evidence suggesting the existence of a distributed neural circuitry regulating amygdala synaptic plasticity during fear learning. This circuitry, which involves projections from the midbrain periaqueductal gray (PAG) region, can be linked to prediction error and expectation modulation of fear learning as described by associative and computational learning models. It controls whether, and how much, fear learning occurs by signalling aversive events when they are unexpected. Functional neuroimaging and clinical studies indicate that this prediction circuit is recruited in humans during fear learning and contributes to exposure-based treatments for clinical anxiety. This aversive prediction error circuit may represent a conserved mechanism for regulating fear learning in mammals.
