So in those cases, the brain’s parietal cortex is charged with assessing which hand makes more sense to perform a specific task. A new study by researchers at UC Berkeley reveals this is actually a competitive process between the two hands, and it’s actually possibly to disrupt the cortex’s decision-making with a little transcranial magnetic stimulation, or TMS.
