| Research Abstract |
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.
