Zapping the brain to boost stroke recovery: small study shows promise

This study tested whether a non-invasive brain stimulation technique called repetitive transcranial magnetic stimulation (rTMS) can improve motor learning in people who had a stroke at least 3 months ago. Twenty participants received rTMS over the part of the brain that processes touch (somatosensory cortex). The goal was to see if this could enhance their ability to learn and perform movements. The study measured brain activity and motor responses, but it was a small, early-stage trial without a control group, so results are limited.
