Sparking Memories With Electrical Stimulation

Sparking Memories With Electrical Stimulation

For years, brain researchers have experimented with electrical stimulation as a way to improve memory, but with mixed results. The problem with these approaches may have been a matter of timing, according to a report published today in the journal Current Biology . Electrical stimulation should be delivered to the brain precisely when memory is predicted to fail—and not when a memory network is operating efficiently, say the authors of the report. The proof-of-concept study offers the first clear indication for when to stimulate the brain in a way that affects memory. The study also marks the first major milestone of the U.S. military’s $77 million program to develop an implantable device that improves memory for people with traumatic brain injury (TBI). DARPA , the research arm of the U.S. Department of Defense, in 2014 began doling out research awards for the program, du...
