MIT researchers have identified the brain circuit required for observational learning, reports Xinhua. According to the study, the area involved in evaluating social information is more active when witnessing an experience and “relays information about the experience” to the region important for processing emotions.
Research by Prof. Susumu Tonegawa suggests that a specific region of the hippocampus plays a role in how memories can trigger a physical stress response, writes Fiona McMillan for Forbes. The findings, McMillan notes, are “providing new insight into the complex interplay between emotion, stress and memory.”
A study by MIT scientists has identified the neurons that fire at the beginning and end of activities, which is important for initiating a routine. “This task-bracketing appears to be important for initiating a routine and then notifying the brain once it is complete,” Prof. Ann Graybiel told Xinhua.
Professor John Gabrieli and graduate student Rachel Romeo speak with WBUR’s Carey Goldberg about their new research. "What we found is, the more often parents engaged in back-and-forth conversation with their child, the stronger was the brain response in the front of the brain to language," Gabrieli explains.
In a Boston Globe Magazine article about bioelectronic medicine, writer Jessie Scanlon highlights research by Profs. Ed Boyden and Daniela Rus. Boyden notes that by creating light-sensitive molecules, which can be switched on and off and inserted into neurons, “groups in academia and industry are using the tool to discover patterns of neural activity.”
Newsweek reporter Joseph Frankel writes that MIT researchers have found that the brain relies on a network of neurons to keep track of time. The researchers found that, “neurons appear to fire in a similar pattern, whether operating at fast or slow speeds...But interestingly, the same patterns stretch or compress over time, depending on the rate of the task.”
MIT researchers have found that a network of neurons compress or stretch their activity in order to control the brain’s timing, reports Alyssa Meyers for The Boston Globe. “Instead of passively waiting for a clock to reach a certain point, the team found the system of neurons changes its state independently based on the action being performed.”
Boston Magazine reporter Jamie Ducharme spotlights Prof. Li-Huei Tsai’s quest to vanquish Alzheimer’s disease. Ducharme writes that Tsai’s work, including two recent papers outlining potential treatments for Alzheimer’s, “established her as a bona fide rock star in the neuroscience world.”
A new study by MIT researchers shows how stress can lead people to make risky decisions, reports Kristin Hugo for Newsweek. “The study lends insights into how neurological disorders affect people. It could be the stress of dealing with inabilities to function properly and staving off cravings, compounded with the chemical effects on the brain, that are influencing people’s uninhibited behavior.”
CNN reporter Jacqueline Howard highlights a new study by MIT researchers examining how children interpret an adult’s emotional response to a situation. "The results were surprising in the sense that we found infants were able to make fine-grained distinctions among positive emotions," explains graduate student Yang Wu.
A new study by MIT researchers shows that different types of learning correspond with different brainwave frequencies, reports Brooks Hays for UPI. The findings, “could help doctors diagnose and treat learning disabilities and cognitive diseases.”
In an article for The Los Angeles Times, Research Scientist Nick Obradovich writes that the way the human brain functions can make it harder for people to take action on climate change. Obradovich notes that, “we’re likely to do better with policies that generate immediate and tangible benefits.”
MIT scientists have discovered that memory creation and memory recall are not connected to the same detour circuit in the brain, reports Alyssa Meyers of the Boston Globe. With this new information, the researchers plan to study how “the circuit functions in the brains of patients with early stages of Alzheimer’s,” explains Meyers.
Jamie Ducharme of Boston Magazine highlights MIT research that increases the resolution and quality of brain scans. The team’s algorithm could fill in missing data from a scan with new pixels, thereby creating a “research-quality image,” explains Ducharme.
Wall Street Journal reporter Alison Gopnik writes about Prof. Pawan Sinha’s research examining how humans acquire specific visual abilities. Sinha’s latest research into how people learn to differentiate between faces and other objects showed that children who had their vision restored were able to learn “the skill and eventually they did as well as sighted children.”
