Prof. Ed Boyden and Prof. Li-Huei Tsai have “found that if gamma waves through non-invasive stimulation, were put back into baseline frequency, it could slow down the process in certain brain diseases such as Alzheimer’s,” reports Hansa Bhargava for Forbes.
Writing for Scientific American, former postdoctoral fellow Aza Allsop PhD '16 and his colleagues spotlight bias in the scientific community. “When the significant contributions of Black scientists are excluded, we all lose,” they write. “This is why it is time that awarding committees and beyond finally begin acknowledging the significant discoveries made by Black scientists that benefit all of humanity—and giving them the proper recognition they deserve.”
New Yorker reporter Rivka Galchen visits the lab of Prof. Hugh Herr to learn more about his work aimed at the “merging of body and machine.” Herr and his team are developing bionic prosthetics that can be completely controlled by the human brain and are designed to allow users “to walk approximately as quickly and unthinkingly as anyone else.” Herr imagines a future where “we will be able to sculpt our own brains and bodies, and therefore our own identities and experiences.”
Prof. Hugh Herr speaks with Nature reporter Fred Schwaller about his work developing bionic limbs. Schwaller notes that “Herr’s research team is focusing on surgical techniques and implants that improve on the electrodes used in current bionic-limb systems, which either penetrate the peripheral nerves or wrap around them.” Herr explains: “We’re reimagining how limbs should be amputated and bionic limbs constructed.”
MIT researchers have created a detailed map showing how the human brain processes information while watching movies, reports Laura Baisas for Popular Science. Using data from functional magnetic resonance imaging (fMRI), researchers uncovered 24 different brain networks that are “associated with specific aspects of sensory or cognitive processing,” explains Baisas.
Prof. Evelina Fedorenko speaks with Scientific American reporter Gary Stix about her research demonstrating that “language and thought are, in fact, distinct entities that the brain processes separately.” Speaking about how large language models could be used to help scientists better understand the neuroscience of how language works, Fedorenko explains that "there are many, many questions that we can now ask that had been totally out of reach: for example, questions about [language] development.”
Profs. Canan Dagdeviren and Hugh Herr speak with CNN discuss their work aimed at empowering patients and doctors. Inspired by her aunt’s experience with breast cancer, Dagdeviren and her students are developing new wearable devices that could help detect cancer at an earlier stage. Says Herr of his work developing prosthetics that can be controlled by the human nervous system: “There will be a point where technology is so sophisticated that we can actually rebuild limbs after amputation that will be as good and, ultimately, they will be better than intact biological limbs.” Herr adds that in the future he hopes “the conversation will not be about human limitation anymore. It will be about human ability and human expression.”
Prof. Li-Huei Tsai, director of the Picower Institute, speaks with NPR host Jon Hamilton about her work identifying a protein called reelin that appears to protect brain cells from Alzheimer's. “Tsai says she and her team are now using artificial intelligence to help find a drug that can replicate what reelin does naturally,” says Hamilton.
MIT scientists have created a high-resolution brain map of the neurons that encode the meanings of various words, reports Sara Reardon for Nature. “The results hint that, across individuals, the brain uses the same standard categories to classify words,” Reardon explains, “helping us to turn sound into sense.”
A new surgical procedure and neuroprosthetic interface developed by MIT researchers allows people with amputations to control their prosthetic limbs with their brains, “a significant scientific advance that allows for a smoother gait and enhanced ability to navigate obstacles,” reports Lizette Ortega for The Washington Post. “We’re starting to get a glimpse of this glorious future wherein a person can lose a major part of their body, and there’s technology available to reconstruct that aspect of their body to full functionality,” explains Prof. Hugh Herr.
Researchers at MIT have developed a novel surgical technique that could “dramatically improve walking for people with below-the-knee amputations and help them better control their prosthetics,” reports Timmy Broderick for STAT. “With our patients, even though their limb is made of titanium and silicone, all these various electromechanical components, the limb feels natural, and it moves naturally, without even conscious thought," explains Prof. Hugh Herr.
Using a new surgical technique, MIT researchers have developed a bionic leg that can be controlled by the body’s own nervous system, reports The Economist. The surgical technique “involved stitching together the ends of two sets of leg muscles in the remaining part of the participants’ legs,” explains The Economist. “Each of these new connections forms a so-called agonist-antagonist myoneural interface, or AMI. This in effect replicates the mechanisms necessary for movement as well as the perception of the limb’s position in space. Traditional amputations, in contrast, create no such pairings.”
A new surgical approach developed by MIT researchers enables a bionic leg driven by the body’s nervous system to restore a natural walking gait more effectively than other prosthetic limbs, reports Clive Cookson for the Financial Times. “The approach we’re taking is trying to comprehensively connect the brain of the human to the electro-mechanics,” explains Prof. Hugh Herr.
Researchers at MIT and Brigham and Women’s Hospital have created a new surgical technique and neuroprosthetic interface for amputees that allows a natural walking gait driven by the body’s own nervous system, reports Adam Piore for The Boston Globe. “We found a marked improvement in each patient’s ability to walk at normal levels of speed, to maneuver obstacles, as well as to walk up and down steps and slopes," explains Prof. Hugh Herr. “I feel like I have my leg — like my leg hasn’t been amputated,” shares Amy Pietrafitta, a participant in the clinical trial testing the new approach.
MIT scientists have conducted a trial of a brain controlled bionic limb that improves gait, stability and speed over a traditional prosthetic, reports Hannah Devlin for The Guardian. Prof. Hugh Herr says with natural leg connections preserved, patients are more likely to feel the prosthetic as a natural part of their body. “When the person can directly control and feel the movement of the prosthesis it becomes truly part of the person’s anatomy,” Herr explains.
