Scientists discover how the brain rewires itself to truly multitask

Georgetown University researchers found that after 5–10 weeks of extensive practice (30,000+ sorting trials), fMRI and EEG scans showed the brain physically reorganizes learned tasks, shifting them from the prefrontal cortex to the temporal cortex, enabling genuine simultaneous task execution rather than rapid switching.

Study used a controlled visual-sorting task; real-world multitasking complexity may differ from the lab paradigm.
