Brain Can Compensate for Cognitive Damage

From a November 3, 2010 Health Day news item

By Robert Preidt

WEDNESDAY, Nov. 3 (HealthDay News) — Undamaged areas of the brain can compensate for damage in a part of the brain called the prefrontal cortex, which is important for memory and attention, a new study finds….

…”Our results show that the neural changes observed in movement recovery after motor cortex damage expand to cognitive domains and apply to a dynamic model of memory and attention compensation by the intact, undamaged cortex,” lead author Dr. Bradley Voytek, University of California at Berkeley, said in a journal news release.

“We demonstrate that brain recovery can manifest itself as transient changes in information processing occurring on a sub-second timescale after the injured brain has been challenged to perform,” he said, adding that this supported “a dynamic and flexible model of [nervous system] plasticity.”

The study appears in the Nov. 4 issue of Neuron
