A little electrical brain stimulation can go a long way in boosting memory.
The key is to deliver a tiny pulse of electricity to exactly the right place at exactly the right moment, a team reports in Tuesday’s Nature Communications.
“We saw a 15 percent improvement in memory,” says Michael Kahana, a professor of psychology at the University of Pennsylvania and an author of the study.
The approach hints at a new way of treating people with memory problems caused by a brain injury or Alzheimer’s disease, Kahana says. But the technology is still far from widespread use.
Kahana has spent years trying to understand why the brain often fails to store information we want it to keep.
