MRIs show the brain radically restructures during coma

Dec 6, 2012 by

The brain radically restructures in comatose (non-traumatized) patients. Using functional MRIs, they found that while the “overall cerebral connectivity” remains, some regions are less connected than in non-comatose patients. In addition, the normally less densely connected regions (in non-comatose patients) become “hubs” when the patient is comatose.
