Abstract
Input specificity is a fundamental property of long-term potentiation (LTP), but it is not known if learning is mediated by synapse-specific plasticity. Kim and Cho (2017) now show that fear conditioning is mediated by synapse-specific LTP in the amygdala, allowing animals to discriminate stimuli that predict threat from those that do not.
摘要
输入特异性是长时程增强（LTP）的一个基本特性，但学习是否由突触特异性可塑性介导尚不清楚。Kim 和 Cho（2017）现在表明，恐惧条件反射是由杏仁核中的突触特异性 LTP 介导的，使动物能够区分预测威胁的刺激与不预测威胁的刺激。
