Electric Stimulation Enhances Cognitive Function, Finds Mega Study

A new meta-analysis of over 100 published studies with more than 2,800 human participants suggests that transcranial alternating current stimulation (tACS), a brain stimulation technology, can improve mental function, particularly executive function, attention, and memory, in both healthy individuals and those with neuropsychiatric conditions. The study also found that a specialized type of tACS that can target two brain regions at the same time can both enhance or reduce cognitive function, which could be particularly useful in the clinic. Improving the design of tACS could help produce stronger, long-lasting changes in mental function.
