Coming soon: a brain implant to restore memory

WASHINGTON - In the next few months, highly secretive US military researchers say they will unveil new advances toward developing a brain implant that could one day restore a wounded soldier's memory.

The Defense Advanced Research Projects Agency (DARPA) is forging ahead with a four-year plan to build a sophisticated memory stimulator, as part of President Barack Obama’s $100 million initiative to better understand the human brain.

The science has never been done before, and raises ethical questions about whether the human mind should be manipulated in the name of staving off war injuries or managing the aging brain.

Some say those who could benefit include the five million Americans with Alzheimer’s disease and the nearly 300,000 US military men and women who have sustained traumatic brain injuries in Iraq and Afghanistan.

"If you have been injured in the line of duty and you can’t remember your family, we want to be able to restore those kinds of functions," DARPA program manager Justin Sanchez said this week at a conference in the US capital convened by the Center for Brain Health at the University of Texas.

"We think that we can develop neuroprosthetic devices that can directly interface with the hippocampus, and can restore the first type of memories we are looking at, the declarative memories," he said.
