MIT researchers have identified the brain circuit that process the “when” and “where” components of memories, reports Robby Berman for Slate. “The newly discovered circuit connects the hippocampus and the entorhinal cortex,” writes Berman. “The entorhinal cortex splits each memory into two streams of information: one for location and one for timing.”
Researchers from MIT, Philips and Boston Medical Center are collaborating on new technology to diagnose brain injuries, reports Nidhi Subbaraman for BetaBoston. “The goal is to investigate whether ultrasound readers can help doctors assess the severity of a head injury,” Subbaraman writes.
In this video, PBS explores a new technique MIT researchers developed to enlarge brain samples, making them easier to image at high resolutions. Prof. Ed Boyden explains that he hopes the technique could be used to “hunt down very rare things in a tissue.”
Doctoral researcher Daniel Goodwin writes for Scientific American about the need for hackers to sort through the vast amount of neuroscience data. “Particularly in a field like neuroscience, helpers could be invaluable in exploring the daunting wilderness of newly revealed neural networks,” Goodwin explains.
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.”
In an article for Bloomberg Business about how poverty can impact brain development in children, John Tozzi highlights research by Prof. John Gabrieli examining how family income can affect academic achievement. "It’s only in the last few years that there’s been any systematic research asking about the biological side of the story," explains Gabrieli.
MIT researchers have found that nitrous oxide or laughing gas is a stronger anesthetic than previously believed, writes Nitya Rajan for The Huffington Post. The researchers found that nitrous oxide caused changes in patient brainwaves and a pattern of electrical firing across the brain.
New research by Prof. Susumu Tonegawa presents the possibility that depression can be alleviated by recalling happy memories, reports Clive Cookson for The Financial Times. The findings suggest, "new ways to treat depression by manipulating memory neurons.”
MIT researchers were able to reverse depression-like behavior by reactivating happy memories, writes Carolyn Gregorie for The Huffington Post. Graduate student and lead author Steve Ramirez “hopes that scientists will one day find a way to prevent depressive symptoms from occurring in the first place.”
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.”
Jessica Hamzelou writes for New Scientist that MIT researchers have been able to recover memories using light. The technique could eventually be used to help people with Alzheimer’s or amnesia. Hamzelou writes that Prof. Susumu Tonegawa, hopes to “develop a way to reactivate forgotten memories in people before the brain tissue itself is damaged, as is often the case in dementia.”
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.”
Guardian reporter Ian Sample writes about research by Bevil Conway, a principal research scientist at MIT, examining why people had different opinions about the color of a dress. Conway found that “our brains devise strategies for working out the true colours of objects in different situations. But because we have different experiences, our brain models differ too.”
