A new study raises hopes for patients with severe amnesia. Memories lost as a result of amnesia can be retrieved by activating certain brain cells with light, a new study says. Researchers at the Massachusetts Institute of Technology (MIT) have managed to recover lost memories of a group of laboratory mice, hit by amnesia, through using a technology known as optogenetics, or the use of light to prompt... 

Scientists have been capable of switching mice’s good memories with bad ones and vice versa. The discovery was the result of work done by a team, formed from a collaboration between Japan’s RIKEN institute and the Massachusetts Institute of Technology in the US. The scientists injected two groups of male mice with light-sensitive algae protein, which enabled them to identify the formation...
