The stimulation targeted frontal and parietal brain areas at different frequencies. Researchers measured changes in brain activity and memory performance during the stimulation.

Active substance
transcranial alternating current stimulation (tACS) device
What this could lead to
If it works, this could point toward a non-invasive way to boost memory in people with brain disorders.
What could go wrong
This is a very small, early feasibility study with only 9 participants. It may not show clear benefits or apply to the general population.
