US researchers are banking on the hope that electrical devices implanted in the brain might one day restore memory to people who have lost it. On 9 July, the US Defense Advanced Research Projects Agency (DARPA) awarded a total of US$37.5 million to two research teams to study how memories are formed and retrieved and to develop devices to stimulate these processes in the brain. Here Nature offers a preview of the research to come from these awards.
Where is the money coming from?
DARPA is one of three US agencies to receive funding this year through the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative, which President Barack Obama announced in April 2013.DARPA has said that it plans to use its share of the money — $50 million this year — to fund study of brain disorders common to soldiers and veterans, such as post-traumatic stress disorder (PTSD) and memory dysfunction caused by traumatic brain injury. In May the agency awarded $56 million to support two teams in creating brain-stimulation devices to treat disorders such as PTSD and depression, and to map the neural circuitry involved in these conditions. The latest round of grants is focused on the use of such devices to restore memory function.
How will the devices be developed?
Both teams will initially be working with people with epilepsy who have entered hospital to have electrodes temporarily implanted into their brains to help locate where their seizures originate. The researchers will ‘piggyback’ off the implants, using them to monitor other brain activity, such as the electrical patterns that occur when the brain is storing or retrieving a memory.
