People with a brain injury or dementia often struggle to remember simple

things, like names or places. In research published Thursday in the journal

Current Biology, scientists have shown it may be possible to improve this

sort of memory using tiny pulses of electricity - if they're properly timed. 

 

A typical person's ability to remember things tends to vary a lot, says

Michael Kahana, who directs the computational memory lab at the University

of Pennsylvania.
