Brain implant could restore lost memory
Washington: US military researchers have revealed that in the next few months, 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-dollar initiative to better understand the human brain, Discovery News reported.
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 that 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.
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, said that they think they could develop neuroprosthetic devices that can directly interface with the hippocampus, and can restore the first type of memories which are the declarative memories.
Declarative memories are recollections of people, events, facts and figures, and no research has ever shown they can be put back once they are lost.
