Electric Brain Stimulation Improves Cognitive Function, Study Finds.

A meta-analysis of over 100 studies on transcranial alternating current stimulation (tACS) has found that it can improve cognitive 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, making it a potentially useful tool in treating specific clinical needs. However, the effectiveness of tACS is still being debated, and further research is needed to improve its design and produce stronger, long-lasting changes in mental function.
