| Research Abstract |
We recorded brainactivitiesin the hippocampus and amygdala, which are involved in memory and emotion,and investigated the time relationship between two brain activities.Theta wavein the amygdala was confirmed to besynchronized with theta wavein the hippocampus. In addition, we found that the synchronization was modulated by the pontine subcoeruleus region, which activates many brain areas including the hippocampus and amygdala.Because hippocampal and amygdalatheta waves are known to be involved in learning and memory processes, these results may help clarify these functions during REM sleep.
