Polina Anikeeva named head of the Department of Materials Science and Engineering
Polina Anikeeva PhD ’09, the Matoula S. Salapatas Professor at MIT, has been named the new head of MIT’s Department of Materials Science and Engineering (DMSE), effective July 1. “Professor Anikeeva’s passion and dedication as both a researcher and educator, as well as her impressive network of connections across the wider Institute, make her incredibly […]
Study reveals how an anesthesia drug induces unconsciousness
There are many drugs that anesthesiologists can use to induce unconsciousness in patients. Exactly how these drugs cause the brain to lose consciousness has been a longstanding question, but MIT neuroscientists have now answered that question for one commonly used anesthesia drug. Using a novel technique for analyzing neuron activity, the researchers discovered that the […]

A prosthesis driven by the nervous system helps people with amputation walk naturally
State-of-the-art prosthetic limbs can help people with amputations achieve a natural walking gait, but they don’t give the user full neural control over the limb. Instead, they rely on robotic sensors and controllers that move the limb using predefined gait algorithms. Using a new type of surgical intervention and neuroprosthetic interface, MIT researchers, in collaboration […]
A new strategy to cope with emotional stress
Some people, especially those in public service, perform admirable feats—healthcare workers fighting to keep patients alive or a first responder arriving at the scene of a car crash. But the emotional weight can become a mental burden. Research has shown that emergency personnel are at elevated risk for mental health challenges like post-traumatic stress disorder. […]
What is language for?
Language is a defining feature of humanity, and for centuries, philosophers and scientists have contemplated its true purpose. We use language to share information and exchange ideas—but is it more than that? Do we use language not just to communicate, but to think? In the June 19, 2024, issue of the journal Nature, McGovern Institute […]

Symposium highlights scale of mental health crisis and novel methods of diagnosis and treatment
Digital technologies, such as smartphones and machine learning, have revolutionized education. At the McGovern Institute for Brain Research’s 2024 Spring Symposium, “Transformational Strategies in Mental Health,” experts from across the sciences — including psychiatry, psychology, neuroscience, computer science, and others — agreed that these technologies could also play a significant role in advancing the diagnosis […]
Just thinking about a location activates mental maps in the brain
As you travel your usual route to work or the grocery store, your brain engages cognitive maps stored in your hippocampus and entorhinal cortex. These maps store information about paths you have taken and locations you have been to before, so you can navigate whenever you go there. New research from MIT has found that […]
