Pulvinar (1 of 2) (image) Princeton University Share Print E-Mail Caption Princeton University researchers have found that the pulvinar, a mysterious region deep in the human brain, acts like a switchboard operator to make sure that separate areas of the brain are communicating about the same external information most important to our behavior at a given moment. The pulvinar uses electrical impulses to synchronize and allow more effective communication between brain cells in the visual cortex, which processes visual information. The researchers produced neural connection maps that show the pulvinar's connection to these brain regions. In this scan, the pulvinar communicates with the occipital lobe (yellow) and the temporal lobe (red) individually, and with both (green).
