| Research Abstract |
In the present study we recorded eye movements, muscle activities, scalp EEG, hippocampal EEG and hippocampal unit activities in the monkey during nocturnal sleep, and analyzed correlation between sleep stages and hippocampal neural activities in order to clarify the functional significant of sleep in the formation and storage of memory in primates. As a results we found that low frequency components of hippocampal EEG increased during non-REM sleep (a period in which memory consolidation is thought to be occur) accompanied by increases in hippocampal activities such as ripples and unit activities. These changes in hippocampal neural activity could be the neural substrate for memory consolidation.
