Scientists strengthen memory by stimulating key site in brain

This undated image provided by the Fried Lab/UCLA shows a brain MRI with an arrow showing where researchers applied deep-brain stimulation during tests on learning. A painless bit of electrical current applied to the brain helped some people play a video game, and someday it might help Alzheimer’s disease patients remember what they’ve learned, a small study suggests. The game-players had to learn where particular stores were in a virtual city. They recalled the locations better if they’d learned them while current was supplied by tiny electrodes buried in their brains. That strategy may someday help people with early Alzheimer’s hang on to many kinds of memory, suggested Dr. Itzhak Fried, a neurosurgeon at the University of California, Los Angeles. But “this is obviously a preliminary result,” he cautioned. (UCLA, Fried Lab)
