Your Brain Can Rewire Itself to Allow True Multitasking

Georgetown University Medical Center researchers used fMRI and EEG to track 11 people through more than 30,000 car-sorting trials.

At first, the task depended mainly on the prefrontal cortex, but with practice more processing shifted to the temporal cortex.

Participants with the biggest brain-activity shift also did better on a second task, suggesting less mental bottlenecking.

The findings suggest trained tasks can move away from effortful executive control, potentially improving real-world multitasking.
