Using FMRI for elucidating dynamic interactions.
For elucidation of information processing mechanism of the human brain, it is important to know dynamic characteristics of functional areas involved in stimulus processing and the functional network consists of those areas. Although it is very difficult to trace the dynamics of neuronal activities with slowly responding signals of functional MRI (fMRI), there is a possibility that some aspects of the dynamics can be probed up to a time scale of tens to hundreds milliseconds by fMRI. Here, we describe some evidences for such possibility in the visual information processing.
