Studies of the brain: Boy recovers normal life after losing big part of his brain

Surgery to remove a brain tumor took much of the patient's vision. But the remaining part of his brain has adjusted.

A boy who lost a large part of his brain to a brain tumor has recovered to a remarkable degree, the rest of his brain having rewired itself to compensate, researchers reported Tuesday.
Surgeons removed a third of one entire lobe of Tanner Collins’ brain to stop seizures caused by a benign brain tumor when he was 6. With it went the entire visual processing center for his left eye. But the remaining part of his brain has adjusted, the team at Carnegie Mellon University in Pittsburgh reported in the journal Cell Reports.
