Abstract

The importance of oscillations in the brain has been discussed experimentally and theoretically in these decades. The author theoretically proposed synchronization oscillation hypothesis first in sensory-memory matching process of visual recognition and extended it to theta rhythm (4~12 Hz) in hippocampus memory system. In both cases, synchronization enables real-time network coordination for real-time computing in novel environments, while the computational theory of brain-type intelligence is still unclear. Recent results of synchronization networks obtained by authors with simultaneous EEG/fMRI measurements indicate different functional roles of different frequency oscillations. In this talk, various frequency oscillations in various cognitive roles are summarized and discussed for further comprehensive understanding of the computational roles of synchronization in the brain.
