模式分离,即相似的经历可以被储存为不同的记忆的过程,被认为是海马体的齿状回(DG)。DG是直接和间接通过基底外侧杏仁核去甲肾上腺素能调节的靶点。我们测试的假设,去甲肾上腺素能激活(测试使用唾液α-淀粉酶)增强DG功能,增强模式分离,通过显示参与者恐惧的刺激在训练前的任务,然后测试他们的能力在以后的测试模式分离。与我们的假设一致,我们发现唾液α淀粉酶水平的增加与增强的模式分离性能呈正相关,即使在考虑了识别的一般增强之后。
Pattern separation, the process by which similar experiences can be stored as distinct memories, has been ascribed to the dentate gyrus (DG) of the hippocampus. The DG is the target of noradrenergic modulation directly and indirectly via the basolateral amygdala. We tested the hypothesis that noradrenergic activation (tested using salivary alpha-amylase) potentiates DG function, enhancing pattern separation, by showing participants fearful stimuli in a pre-training task and then testing their capacity for pattern separation in a later test. Consistent with our hypothesis, we found that increased levels of salivary alphaamylase were positively correlated with enhanced pattern separation performance even after accounting for general enhancements in recognition.
