Abstract
We study changes of EEG coherence induced by cognitive activation of the brain in healthy subjects. Coherence is considered a correlation coefficient between two electrical signals and may reflect the functional relationships between brain areas. Local coherence is calculated on paired adjacent scalp EEG electrodes whereas inter- regional coherence also includes nonadjacent paired electrodes. We developed a color computer animation display method allowing us to visualize the intensity and regional spatial distribution of coherence changes in time during a cognitive activation process.
