According to AFP, MIT researchers were able to use a technology called optogenetics to retrieve lost memories. Professor Susumu Tonegawa explains that the research showed, “past memories may not be erased, but could simply be lost and inaccessible for recall."

Graduate student Dheeraj Roy speaks with Rachel Paiste of WBUR about a new study that indicates that memories lost to amnesia may be recalled by activating brain cells with light. Roy explains that the findings show that “in certain models of amnesia, memories do persist.”
