Each point measures the synchrony (correlation) of spontaneous brain activity with that of the cingulate cortex. Rows are brain regions (space), columns are time windows. Rows have been ordered to expose the spatial structure of synchrony. Non-linear deformation of the space/time grid have been applied to expand outlier synchrony values, and visually emphasize their importance. This may turn out to be a useful trick to explore space-time dynamics, or not.
