On the role of amygdala in emotional response during REM sleep

杏仁核中超过一半的神经元在REM睡眠期间比其他阶段（清醒和慢波睡眠）表现出更高的活性。这些神经元在REM睡眠中并不持续放电，而是在REM睡眠的某个限定时期表现出阶段性或爆发性放电。一些杏仁核神经元的放电与血压的大幅波动同步。这些结果提示杏仁核在快速眼动睡眠期自主神经系统的变化中起着重要的作用，而自主神经系统的变化与快速眼动睡眠期的情绪变化密切相关。

More than half of the neurons in the amygdala showed higher activity during REM sleep than during other stages (wakefulness and slow wave sleep). These neurons did not fire continuously through REM sleep, but showed phasic or burstic firing at some restricted period of REM sleep. Some of the amygdala neurons displayed firing in synchronous with large fluctuations of blood pressure. These results suggest that the amygdala have crucial roles in the changes of autonomic nervous system occurring during REM sleep, which would be closely related with emotional changes during REM sleep.
