MIT researchers have found that cell stimulation may one day be a tool in helping Alzheimer’s patients recall lost memories, according to The Guardian. The findings raise “the possibility of future treatments that reverse memory loss in early stages of the disease.”
Wired reporter Emily Reynolds writes that MIT neuroscientists have identified the region of the brain that generates a feeling of loneliness. The researchers found that the “DRN, near the back of the brain, hosts a cluster of cells that the team say is responsible for generating increased sociability after periods of isolation.”
In this Today Show segment, Prof. Earl Miller and Prof. Robert Desimone discuss how the brain reacts to the information overload that comes from using multiple digital tools at once. “The brain has a great deal of difficulty processing multiple bits of data at once,” explains Miller. "We are very, very single minded.”
Postdoctoral fellow Steve Ramirez speaks with Bob Seay, host of WGBH’s Morning Edition, about his work with memory manipulation, which could be helpful for patients with PTSD or Alzheimer’s. Ramirex explains that his research shows the proof of principle “that we can go in and isolate one memory in the brain.”
Karen Weintraub writes for The Boston Globe about Prof. Susumu Tonegawa’s research examining how triggering happy memories could help alleviate depression. “When that kind of technology is invented,” Tonegawa explains, “it could potentially become very powerful therapy.”
Professor Susumu Tonegawa’s research group has found that artificially stimulating positive memories can ease depression, reports Jonathan Webb for BBC News. Webb explains that the research “demonstrates the power of rekindling happy memories.”
Washington Post reporter Rachel Feltman writes that MIT researchers have used optogenetics to reactive lost memories. The research indicates that, “retrograde amnesia -- where memories are lost after brain trauma -- may be more of a memory retrieval problem than an actual loss of data.”
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.”
