You learned that activation of specific brain regions can make memories stronger!
Electrical activity in specific brain cells allows us to create and recall memories. BRAIN Initiative scientists used new tools to send tiny electrical currents to patients' brain cells and found that their memories became stronger. This could help us improve therapies and treat memory disorders in the future.
