Prof. Ann Graybiel speaks with Forbes contributor Pat Brans about age and habit formation. Graybiel explains that she does not think “it’s ever too late to change habits or to make new ones,” adding that “‘habit’ patterns in the brain have to get renewed reinforcement from time to time.”
Scientific American reporter Veronique Greenwood highlights a study by MIT researchers examining why some people seem to have an aptitude for languages. The researchers explored the structure of neuron fibers in white matter in beginning Mandarin students and found that students “who had more spatially aligned fibers in their right hemisphere had higher test scores after four weeks of classes.”
TIME reporter Alice Park writes about a study by Prof. John Gabrieli that shows that the difficulty people with dyslexia experience when reading could be caused by reduced plasticity in the brain. “We need to figure out a curriculum or approach that matches the differences they have,” explains Gabrieli.
A new study co-authored by Prof. John Gabrieli shows that the brains of people with dyslexia respond differently not only to words, but also objects and faces, reports Felice Freyer for The Boston Globe. The findings point to “the core biological difference in the brains of people with dyslexia,” explains Prof. John Gabrieli.
MIT researchers have found that flashing lights could potentially be used to stave off Alzheimer’s disease, writes Oscar Williams for The Huffington Post. “Light stimulation directed to the hippocampus, the part of the brain that processes memories, led to a reduction of…beta amyloid,” which is found in Alzheimer’s disease.
Financial Times reporter Clive Cookson writes that MIT researchers have found evidence that flashing lights could potentially be used as a noninvasive treatment for Alzheimer’s disease. The researchers found that “lights flashing on and off 40 times per second restored ‘gamma oscillation’ waves that were suppressed in the disease.”
MIT researchers have found that flashing light may reduce the buildup of beta amyloid protein in the brain, which is associated with Alzheimer’s disease, writes Michelle Roberts for the BBC News. The researchers hope that “clearing beta amyloid and stopping more plaques from forming could halt Alzheimer's and its symptoms.”
Writing for The Atlantic, Ed Yong spotlights a study by MIT researchers that identifies a potential new treatment for Alzheimer’s – using pulses of light to stimulate brain waves. Yong writes that the study “heralds a completely new approach to dealing with Alzheimer’s—changing neural activity, rather than delivering drugs or chemicals.”
MIT researchers have found that exposure to flickering lights at a precise frequency may help fight off Alzheimer’s disease, reports Melissa Healy for The Los Angeles Times. The technique recruits “neurons and other cell types in the brain to sort of enable the brain’s inner ability to repair itself,” explains Prof. Li-Huei Tsai, director of the Picower Institute.
Guardian reporter Hannah Devlin writes about a new study by MIT researchers that shows that strobe lighting can reduce levels of toxic proteins found in Alzheimer’s disease. The researchers found that “exposure to flickering light stimulated brain waves, called gamma oscillations, that are known to be disturbed in Alzheimer’s patients.”
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.
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.
MIT neuroscientists have identified two regions of the brain involved in creating panoramic memories, writes Tara Pattilachan for The Huffington Post. “Our understanding of our environment is largely shaped by our memory for what’s currently out of sight,” says postdoc Caroline Robertson of the importance of understanding how our brains develop panoramic memories.
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.”
MIT researchers have discovered that a bacterium found in the human mouth can be used to form a new CRISPR gene-editing system that can target RNA, reports Carl Zimmer for The New York Times. The development “may open up a new front in gene engineering, gaining the ability to precisely adjust the proteins in cells, for instance, or to target cancer cells."
