Abstract

Using event-related fMRI, Wittmann and colleagues report in this issue of Neuron that reward value enhances cue memory and that this process is associated with midbrain modulation of hippocampal consolidation. We propose that their findings introduce a novel mechanism by which positive arousal induced by reward anticipation may promote memory.

摘要

维特曼及其同事在本期《神经元》杂志上发表报告称，利用事件相关功能磁共振成像技术发现，奖励价值可增强线索记忆，且这一过程与海马体巩固过程中的中脑调节有关。我们认为，他们的研究结果引入了一种新机制，即奖励预期所引发的积极唤醒可能会促进记忆。
