Researchers turn long-term memories on and off with the flip of a switch

Researchers turn long-term memories on and off with the flip of a switch: "Using electrical probes embedded into the brains of rats, scientists have managed to replicate the brain function associated with long-term behavior and found a way to literally turn memories on and off with the flip of a switch. The scientists hope their research will eventually lead to a neural prosthesis to help people suffering Alzheimer's disease, the effects of stroke or other brain injury to recover long-term memory capability."
