As they age, adults experience less negative emotion, come to pay less attention to negative than to positive emotional stimuli, and become less likely to remember negative than positive emotional materials. This profile of findings suggests that, with age, the amygdala may show decreased reactivity to negative information while maintaining or increasing its reactivity to positive information. We used event-related functional magnetic resonance imaging to assess whether amygdala activation in response to positive and negative emotional pictures changes with age. Both older and younger adults showed greater activation in the amygdala for emotional than for neutral pictures; however, for older adults, seeing positive pictures led to greater amygdala activation than seeing negative pictures, whereas this was not the case for younger adults.
随着年龄的增长，成年人经历的负面情绪减少，对负面情绪刺激的关注少于对正面情绪刺激的关注，并且记住负面情绪材料的可能性低于记住正面情绪材料的可能性。这些研究结果表明，随着年龄的增长，杏仁核可能对负面信息的反应性降低，同时对正面信息的反应性保持或增加。我们使用事件相关功能磁共振成像来评估杏仁核对正面和负面情绪图片的激活是否随年龄而变化。老年人和年轻人在看到情绪图片时杏仁核的激活都比看到中性图片时更强；然而，对于老年人来说，看到正面图片比看到负面图片会导致更强的杏仁核激活，而年轻人则并非如此。
