行为数据表明，漂亮的面孔更容易被记住，但这种影响的神经机制在很大程度上是未知的。为了研究这个问题，研究人员对女性参与者进行了事件相关功能核磁共振成像（fMRI）扫描，同时给男性面孔的吸引力打分。在fMRI扫描后对面孔进行记忆测试，并用于识别成功的编码活动（后续记忆范式）。正如预期的那样，漂亮的面孔比其他面孔更容易被记住。这项研究产生了三个主要的fMRI发现。首先，右眼额叶皮层的活动随着吸引力评分呈线性增加。其次，左侧海马体的活动随着后续记忆的增加而增加（后续记忆缺失<低信心命中<高信心命中）。第三，在对有吸引力的面孔进行编码时，这些眶额区和海马区之间的功能连通性比中性或无吸引力的面孔更强。这些结果表明，对漂亮面孔的更好记忆反映了与奖励相关的区域眶额皮质和与成功记忆编码相关的区域海马体之间更大的相互作用。
Behavioral data have shown that attractive faces are better remembered but the neural mechanisms of this effect are largely unknown. To investigate this issue, female participants were scanned with event-related functional MRI (fMRI) while rating the attractiveness of male faces. Memory for the faces was tested after fMRI scanning and was used to identify successful encoding activity (subsequent memory paradigm). As expected, attractive faces were remembered better than other faces. The study yielded three main fMRI findings. First, activity in the right orbitofrontal cortex increased linearly as a function of attractiveness ratings. Second, activity in the left hippocampus increased as a function of subsequent memory (subsequent misses<low-confidence hits<high-confidence hits). Third, functional connectivity between these orbitofrontal and hippocampal regions was stronger during the encoding of attractive than neutral or unattractive faces. These results suggest that better memory for attractive faces reflects greater interaction between a region associated with reward, the orbitofrontal cortex, and a region associated with successful memory encoding, the hippocampus.
