Abstract (in Japanese) (See Japanese page) 
(in English) There is a large number of studies showing that REM sleep contributes memory consolidation. The mechanism of the memory consolidation during REM sleep is not clear, but hippocampal theta waves and PGO waves are suggested to be involved in the memory processes. In this study, we have recorded the theta waves and PGO waves during REM sleep in fear-conditioned rats to clarify the mechanism. We found that frequency of hippocampal theta waves and PGO wave densities were increased just after the fear learning. These results suggest that PGO and theta waves contribute cooperatively to the REM sleep dependent memory consolidation.
