#MentalFlexibility

A new study from Germany has found that a gentle, non-invasive brain stimulation technique—transcranial direct current stimulation (tDCS)—can subtly influence how quickly and flexibly people make decisions. In an experiment targeting a brain area deeply involved in planning and decision processes, researchers discovered that the type of stimulation applied was linked to either quicker choices or greater mental rigidity in volunteers. The findings not only shed light on the brain’s role in cognitive flexibility but raise timely questions for those in Thailand and across Asia interested in brain-boosting gadgets or educational interventions promising sharper thinking.
