STAT reporter Meghana Keshavan speaks with Prof. Guoping Feng about his new research that shows glial cells “very actively participate in direct neuronal function — particularly in the brain areas that control appetite, energy and metabolism.” The findings could help spur the development of weight loss medications.
Adam Piore spotlights Prof. Earl Miller’s research into the mechanisms behind working memory in an article for Discover. “Earl is kind of a rock star,” says Prof. Brad Postle of the University of Wisconsin-Madison. “When he says something, a lot more people notice it.”
MIT researchers have identified a region of the brain responsible for forming habits, reports Anil Ananthaswamy for New Scientist. The researchers found that when performing an action, the prefrontal cortex, communicates with the striatum. “Over time, input from the prefrontal circuits fades, to be replaced by loops linking the striatum to the sensorimotor cortex,” Ananthaswamy explains.
Writing for The New York Times, Steve Lohr features Prof. Tomaso Poggio’s work “building computational models of the visual cortex of the brain, seeking to digitally emulate its structure, even how it works and learns from experience.” Lohr notes that efforts like Poggio’s could lead to breakthroughs in computer vision and machine learning.
Writing for The New York Times, Katie Hafner highlights how MIT researchers have identified a region of the brain that they believe could be responsible for producing feelings of loneliness. Hafner explains that “the region, known as the dorsal raphe nucleus, or D.R.N., is best known for its link to depression.”
Inside Higher Ed reporter Colleen Flaherty writes that researchers from MIT and around the world are publicly defending the late Prof. Suzanne Corkin’s work with patient H.M. in response to a highly critical publication. When “so many scholars rise to defend the reputation of a deceased colleague,” says Arthur Caplan, head of NYU’s Division of Bioethics, “that speaks volumes both about her and the problems that exist in the book.”
Prof. Emerita Suzanne Corkin, whose work with a famous amnesia patient was instrumental in uncovering the nature of memory, died on May 24, reports Benedict Carey for The New York Times. Carey writes that Corkin’s work “helped settle a debate about the function of the hippocampus in retrieving and reliving past experiences.”
Prof. Earl Miller speaks with Meghna Chakrabarti, host of Radio Boston, about the dangers of distracted driving. Miller explains that our brains “have a very limited capacity for simultaneous thought.” He adds that people have a hard time ignoring their phones while driving because the “brain evolved to find new information rewarding.”
Helen Shen writes for Nature that MIT researchers have developed a technique for assembling and operating an automated system for “whole-cell patch-clamping”, a method of monitoring the activity of brain cells. “Our hope is that we can help as many people as possible to answer questions about how neurons compute,” explains Prof. Edward Boyden.
MIT researchers have found a possible link between attention deficit disorders and autism, reports Lindsay Kalter for The Boston Herald. “One of the long-term goals is gene therapy where we can actually introduce genetic material that might be missing from the human,” explains grad. student Michael Wells.
Popular Science reporter Claire Maldarelli writes that researchers from MIT have identified how sensory overload occurs for people with neurodevelopmental disorders. Based off their findings, the researchers hope they can "classify these disorders in a better way, but also develop therapies that alleviate or diminish the symptoms.”
MIT researchers have shown that memories can be restored using optogenetics, findings that could help treat Alzheimer’s. According to The Economist, the findings provide evidence “about how memories are lost during the early stages of the disease and may point to how…those memories might be brought back.”
A new study conducted by MIT researchers suggests that optogenetics could one day be used to help stimulate lost memories in Alzheimer’s patients, reports Ashley Welch for CBS News. Walsh writes that the researchers have “found evidence that ‘lost’ memories may just be inaccessible, with the potential to be retrieved.”
In an article posted by Scientific American, Sara Reardon writes that MIT researchers have shown that patients with Alzheimer’s can still form new memories and that lost memories could potentially be recalled using optogenetics. The findings “may allow more targeted stimulation, especially once researchers understand what happens to memories after they leave the hippocampus.”
Huffington Post reporter Ann Brenoff writes about a new MIT study that finds that Alzheimer’s patients may one day be able to recover lost memories using optogenetics. “The findings raise the hope — and possibility — that future treatments might indeed reverse some of the memory loss in early-stage Alzheimer’s patients.”
