Researchers at MIT have found that the brain can send a burst of noradrenaline when it requires you to pay attention to something crucial, reports Juandre for Popular Mechanics. “The MIT team discovered that one important function of noradrenaline, commonly known as norepinephrine, is to assist the brain in learning from unexpected results,” explains Juandre.
USA Today reporter Karen Weintraub spotlights Prof. Li-Huei Tsai’s work studying a potential new approach to treating Alzheimer's disease and “whether certain tones of sound and frequencies of light can help regulate brain waves and help clear our cellular trash, including toxic proteins.” Tsai explains that: “The major difference between this approach and all other approaches is that this approach doesn’t just target one molecule or one pathway or one cell type. This is a holistic approach to take care of the whole system.”
Writing for The Boston Globe, Prof. Li-Huei Tsai underscores the need for the Alzheimer’s research community to “acknowledge the gaps in the current approach to curing the disease and make significant changes in how science, technology, and industry work together to meet this challenge.” Tsai adds: “With a more expansive mode of thinking, we can bridge the old innovation gaps and cross new valleys of discovery to deliver meaningful progress toward the end of Alzheimer’s.”
Prof. Mark Bear speaks with NPR’s Jon Hamilton about how injecting tetrodotoxin, a paralyzing nerve toxin found in puffer fish, could allow the brain to rewire in a way that restores vision and help adults with amblyopia or "lazy eye." Bear explains that: “Unexpectedly, in many cases vision recovered in the amblyopic eye, showing that that plasticity could be restored even in the adult.”
NPR’s Jon Hamilton spotlights Prof. Li-Huei Tsai’s work developing a noninvasive technique that uses lights and sounds aimed at boosting gamma waves and potentially slowing progression of Alzheimer’s disease. "This is completely noninvasive and could really change the way Alzheimer's disease is treated," Tsai says.
Reporting for Good Morning America, Kate Kindelan spotlights how Prof. Troy Littleton has placed a travel crib in one of his lab’s offices so his graduate student, Karen Cunningham, can bring her 10-month-old child to work with her when needed. “These sort of local ways that people in positions of power can protect parents against the systemic things, like what Troy's been doing in creating a really supportive and inclusive lab, I think that does make a really big difference and it's great to have an example of that,” says Cunningham.
Wired reporter Max Levy spotlights Prof. Emery Brown and Earl Miller’s research examining how neurons in the brain operate as “consciousness emerges and recedes—and how doctors could better control it.” Levy writes that “Miller and Brown's work could make anesthesia safer, by allowing anesthesiologists who use the EEG to more precisely control drug dosages for people who are unconscious.”
Scientific American reporter Leslie Nemo spotlights postdoctoral fellow Matheus Victor’s photograph of a petri dish full of neurons. Nemo writes that Victor and his colleagues hope the “rudimentary brain tissue will reveal why a new therapy might alleviate Alzheimer’s symptoms.”
Boston Globe reporter Corrie Pikul spotlights Prof. Li-Huei Tsai’s work finding that exposure to a specific pattern of rhythmic lights and sound bursts could potentially serve as a non-invasive treatment for Alzheimer’s. “These are really surprising findings,” says Tsai. “We are seeing multiple different cellular responses that are consistent with increased brain health.”
Dr. Francis Collins, director of the NIH, spotlights a video created by Prof. Kwanghun Chung that takes viewers on a voyage through a region of the brain that controls voluntary movement. Thanks to imaging techniques like Chung’s, “mapping the biocircuitry of the brain just keeps getting better all the time,” Collins explains.
Popular Science reporter Nicole Wetsman writes that MIT researchers have found light pulses could potentially be used to help ease the symptoms of Alzheimer’s disease. The researchers found that “light pulses and gamma oscillations protect against neurodegeneration and change the expression of genes involved with inflammation and neuron health in the brains of mice.”
A gift from alumnus Charles Broderick will enable researchers at MIT and Harvard to investigate how cannabis effects the brain and behavior, reports Felice Freyer for The Boston Globe. Prof. John Gabrieli explains that it has been “incredibly hard” to get funding for marijuana research. “Without the philanthropic boost, it could take many years to work through all these issues,” he notes.
WBUR reporter Carey Goldberg spotlights how a gift from alumnus Charles Broderick is funding research on cannabis and its impacts on the brain. "We were saying, 'Wouldn't it be great to study this?'” says Prof. Myriam Heiman of the need to study the impacts of cannabis. "And then this gift comes along and really is enabling us to do everything we wanted to do."
Los Angeles Times reporter Melissa Healy writes that a new study by MIT researchers provides evidence that acoustic and visual stimulation could improve Alzheimer’s symptoms. “The study’s central finding — that inducing electrical synchrony touched off such a widespread range of effects — suggests there might be a single key lever that can preserve or restore order in brains made 'noisy' by age and disease,” Healy explains.
A study by MIT researchers shows that exposing patients to flashing light and pulsing sounds could reverse Alzheimer’s symptoms, reports Angus Chen for Scientific American. “This is the first time we’ve seen that this noninvasive stimulation can improve cognitive function,” says Prof. Li-Huei Tsai.
