Outline of Final Research Achievements

Sleep has been thought having an important function for memory consolidation. In the present study, however, we showed that memory consolidation related to visuomotor learning was not related to sleep, at least 90 minutes afternoon nap consisted of both the rapid eye movement (REM) sleep and non-REM sleep. The role of sleep might be different between 90 minutes afternoon nap and full of night sleep including 4-5 cycles of REM and non-REM sleeps. In addition to that, we found out that visuomotor learning occurred unrelated to subjective feeling of “fun.” This indicates that implicit type of learning might occur unrelated to the emotion, at least positive emotion such as fun. Conducting the present research, we could get useful information and ideas for future researches.
