| Outline of Final Research Achievements |
Working memory is a memory system which sustains concurrent execution of temporary storage and process of information. It is considered as a basis of higher cognitive activities. The purpose of this research is to explore the function of central executive component of working memory, by clarifying the activity of working memory and its brain mechanisms under the unconscious condition. Mainly, we explored how the activity of the central executive change under the anesthetized conscious condition which is similar to pseudo memory dysfunction. It showed that under the 50% concentration of anesthetized condition, it is possible to execute the dual-task which is the typical working memory situation. On the other hands, under the same anesthetized condition, participants could not transform the information into the long-term memory. We speculate that the 50% concentration of anesthetized condition is the threshold level of consciousness under which working memory system can work effectively.
