Rapid functional reorganization in human cortex following neural perturbation

You have to demand your doctor figure out how the last line occurs. Even if its too late for you the next patient needs this information. Your doctors won't do a damn thing if you don't insist they  plan a stroke protocol around something like this. Unless they can prove it is not accurate.

Abstract

Despite the human brain's ability to rapidly reorganize neuronal activity patterns in response to interactions with the environment (e.g., learning), it remains unclear whether compensatory mechanisms occur, on a similar time scale, in response to exogenous cortical perturbations. To investigate this, we disrupted normal neural function via repetitive transcranial magnetic stimulation and assessed, using fMRI, activity changes associated with performance on a working memory task. Although transcranial magnetic stimulation disrupted neural activity in task-related brain regions, performance was not affected. Critically, another brain region not previously engaged by the task was recruited to uphold memory performance. Thus, functional reorganization of cortical activity can occur within minutes of neural disruption to maintain cognitive abilities.
