| Outline of Final Research Achievements |
We refer to the awareness of time, over the past, present and future, as the “mental time”. This project aimed at elucidating neural basis for the flow of time around the “present” in particular. Our study has shown that 1) the alpha-band rhythm with its source located in the medial surface of the cerebral cortex (precuneus) plays an essential role in the determination of temporal order between two successive events, 2) the precuneus responds strongly to verbal stimuli that refer to the present, and 3) the precuneus represents an allocentric spatial coordinate that is fixed to the external world. From these findings, we infer that the precuneus is responsible for producing our awareness of the present events by localizing each sensory signal to a relevant location in space in a relevant order in relation to the other signals.
