Kaiser Health News: “A new study looks at the effects of electrical stimulation on the brain, and how those pulses can improve and impair memory.”

• The New York Times: ‘Pacemaker’ For The Brain Can Help Memory, Study Finds  – Well-timed pulses from electrodes implanted in the brain can enhance memory in some people, scientists reported on Thursday, in the most rigorous demonstration to date of how a pacemaker-like approach might help reduce symptoms of dementia, head injuries and other conditions.
• NPR: Clues To Failing Memory Found In Brain Stimulation Study  – “When memory was predicted to be poor,” he explains, “brain stimulation enhanced memory, and when it was predicted to be good, brain stimulation impaired memory. “In other words, on a bad memory day, stimulation helped. On a good day, it hurt. When stimulation was delivered to the right place at the right time, the researchers found, it could improve memory performance among the patients by as much as 50 percent.”
