Decision makers rely on episodic memory to calculate choice values in everyday life, yet it is unclear how neural mechanisms of valuation differ when value-related information is encoded versus retrieved from episodic memory. The current fMRI study compared neural correlates of value while information was encoded versus retrieved from memory. Scanned tasks were followed by a behavioral episodic memory test for item-attribute associations. Our analyses sought to (i) identify neural correlates of value that were distinct and common across encoding and retrieval, and (ii) determine whether neural mechanisms of valuation and episodic memory interact. The study yielded three primary findings. First, value-related activation in the fronto-striatal reward circuit and posterior parietal cortex was comparable across valuation phases. Second, value-related activation in select fronto-parietal and salience regions was significantly greater at value retrieval than encoding. Third, there was no interaction between neural correlates of valuation and episodic memory. Taken with prior research, the present study indicates that fronto-parietal and salience regions play a key role in retrieval-dependent valuation and context-specific effects likely determine whether neural correlates of value interact with episodic memory.

决策者依靠情景记忆来计算日常生活中的选择值，但尚不清楚当价值相关信息被编码与从情景记忆中检索时，估值的神经机制有何不同。当前的 fMRI 研究比较了信息在编码和从记忆中检索时的神经价值相关性。扫描任务之后是项目属性关联的行为情景记忆测试。我们的分析旨在 ( i ) 识别在编码和检索中不同且共同的价值的神经相关性，以及 ( ii )) 确定评估和情景记忆的神经机制是否相互作用。该研究产生了三个主要发现。首先，额纹状体奖励回路和后顶叶皮层中的价值相关激活在评估阶段具有可比性。其次，选择额顶叶和显着区域的价值相关激活在价值检索时明显大于编码。第三，评估的神经相关性和情景记忆之间没有相互作用。结合先前的研究，本研究表明，额顶和显着区域在依赖于检索的评估中起着关键作用，并且特定于上下文的影响可能决定了价值的神经相关性是否与情景记忆相互作用。
