MIT researchers have identified the region of the brain that perceives music, reports Emily Reynolds for Wired. The researchers found that one area of the brain “responded most to music, another to speech, and the other four to different acoustic properties such as pitch and frequency.”
Huffington Post reporter Lila Shapiro speaks with Robert Desimone, director of the McGovern Institute, about the use of the CRISPR gene-editing technique to treat neurological diseases. “CRISPR’s impact is potentially across the board,” says Desimone. “It went from nothing just a few years ago to being a tool that’s in everyone’s toolbox.”
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.”
Prof. John Gabrieli speaks with WGBH’s Arun Rath about the effectiveness of standardized testing in the U.S. Gabrieli explains that researchers have, “consistently found academic achievement tests of the kind given by states in the United States correlate considerably with other independent measures of cognitive ability.”
STAT reporter Andrew Joseph writes about optogenetics and Prof. Edward Boyden’s work developing this technique for turning neurons on and off. “There are just huge frontiers out there for which optogenetics will be one of our most powerful tools,” said Robert Desimone, director of the McGovern Institute.
Boston Globe reporter Felicia Gans writes that a number of MIT researchers have been honored “by the Breakthrough Prize organization, which honors scientists worldwide for their pioneering research.”
Prof. Edward Boyden has been honored as one of the recipients of the Breakthrough Prize, reports Sarah McBride for Reuters. Boyden is being recognized for his work “developing and implementing optogenetics,” writes McBride, which could open “a new path to treatments for Parkinson’s, depression, Alzheimer’s and blindness.”
Writing for Scientific American, Simon Makin explores the many applications of optogenetics, a tool developed by Prof. Edward Boyden, for which he was recently honored with a Breakthrough Prize. Makin explains that, “researchers have devised ways of broadening optogenetics to enter into a dynamic dialogue with the signals moving about inside functioning brains.”
In an article for Science, Rhitu Chatterjee writes about Project Prakash, an effort started by Prof. Pawan Sinha to help children with preventable or treatable blindness see. Chatterjee writes that the project has brought hundreds of young people, “into the light—while putting the field of visual neuroscience in a new light as well.”
Writing for BetaBoston, Nidhi Subbaraman reports that Prof. Polina Anikeeva has received a new grant from DARPA to investigate ways to stimulate specific neurons in the body using fibers or nanoparticles. “Zapping key nerves with a current, ultrasound, or with light is expected to treat a range of conditions,” Subbaraman explains.
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.”
