阅读他人情绪并对其做出适当反应的能力是成功社交的核心。年轻人和老年人更善于识别积极的面部表情而不是消极的面部表情，年轻人的表情也比年长的面部表情更好。然而，在年轻人和老年人的样本中，对与阅读不同情绪有关的神经过程知之甚少，特别是在不同年龄的面孔上。在功能磁共振成像过程中，年轻的和年长的参与者识别了年轻人和老年人高兴、中立和愤怒的表情。结果表明，在阅读面部情绪时，腹内侧前额叶皮质(VmPFC)和背内侧前额叶皮质(DmPFC)的功能分离在年轻人和老年人中基本相似：两个年龄组的vmPFC比愤怒或中性面孔都表现出更大的vmPFC活性，这与对高兴的表情识别比对愤怒面孔的识别呈正相关。相反，两个年龄组在中性或愤怒表情的dmPFC上表现出比快乐面孔更大的活动，这与中性表情识别比快乐面孔的表情识别呈负相关。DmPFC的类似区域显示，年龄较大的人比年轻的人更活跃，但大脑行为没有相关性。与中性或愤怒的面孔相比，本研究中较大的vmPFC活动可能反映出阅读快乐时涉及更多的情感处理。更大的dmPFC活动可能反映了更多的认知控制，涉及到解码和/或调节与中性或愤怒相关的负面情绪，而不是快乐的、年长的、比年轻的面孔。
The ability to read and appropriately respond to emotions in others is central for successful social interaction. Young and older adults are better at identifying positive than negative facial expressions and also expressions of young than older faces. Little, however, is known about the neural processes associated with reading different emotions, particularly in faces of different ages, in samples of young and older adults. During fMRI, young and older participants identified expressions in happy, neutral, and angry young and older faces. The results suggest a functional dissociation of ventromedial prefrontal cortex (vmPFC) and dorsomedial prefrontal cortex (dmPFC) in reading facial emotions that is largely comparable in young and older adults: Both age groups showed greater vmPFC activity to happy compared to angry or neutral faces, which was positively correlated with expression identification for happy compared to angry faces. In contrast, both age groups showed greater activity in dmPFC to neutral or angry than happy faces which was negatively correlated with expression identification for neutral compared to happy faces. A similar region of dmPFC showed greater activity for older than young faces, but no brain-behavior correlations. Greater vmPFC activity in the present study may reflect greater affective processing involved in reading happy compared to neutral or angry faces. Greater dmPFC activity may reflect more cognitive control involved in decoding and/or regulating negative emotions associated with neutral or angry than happy, and older than young, faces.
