How the brain quickly rebounds from injuries. It quickly switches to secondary backup areas, scientists find.
Scientists at Carnegie Mellon University‘s Center for Cognitive Brain Imaging (CCBI) have used a new combination of neural imaging methods to discover exactly how the human brain adapts to injury.
When one brain area loses functionality, a “back-up” team of secondary brain parts immediately activates, replacing not only the unavailable area but also its confederates (connected areas), the research shows.
The research found that as the brain function in the Wernicke area decreased following the application of rTMS (transcranial magnetic stimulation), a “back-up” team of secondary brain areas immediately became activated and coordinated, allowing the individual’s thought process to continue with no decrease in comprehension performance.
