Study provides new evidence that sensory stimulation of gamma-frequency brain rhythm may promote broad-based restorative neurological health response. Studies by a growing number of labs have identified neurological health benefits from exposing human volunteers or animal models to light, sound and/or tactile stimulation at the brain’s “gamma” frequency rhythm of 40Hz. In the latest such …
A decade of studies from labs around the world provide a growing evidence base that increasing the power of the brain’s gamma rhythms could help fight Alzheimer’s, and perhaps other, neurological diseases. A decade after scientists in The Picower Institute for Learning and Memory at MIT first began testing whether sensory stimulation of the brain’s …
MIT scientists report that gamma frequency light and sound stimulation preserves myelination in mouse models and reveal molecular mechanisms that may underlie the benefit. Early-stage trials in Alzheimer’s disease patients and studies in mouse models of the disease have suggested positive impacts on pathology and symptoms from exposure to light and sound presented at the “gamma” band …
Genomics and lab studies reveal numerous findings, including a key role for Reelin amid neuronal vulnerability, and for choline and antioxidants in sustaining cognition An MIT study published today in Nature provides new evidence for how specific cells and circuits become vulnerable in Alzheimer’s disease, and hones in on other factors that may help some people show …
Stimulating gamma brain waves may protect cancer patients from memory impairment and other cognitive effects of chemotherapy. Patients undergoing chemotherapy often experience cognitive effects such as memory impairment and difficulty concentrating — a condition commonly known as “chemo brain.” MIT researchers have now shown that a noninvasive treatment that stimulates gamma frequency brain waves may …
Stimulating a key brain rhythm with light and sound increases peptide release from interneurons, driving clearance of Alzheimer’s protein via the brain’s glymphatic system, new study suggests. Studies at MIT and elsewhere are producing mounting evidence that light flickering and sound clicking at the gamma brain rhythm frequency of 40 Hz can reduce Alzheimer’s disease (AD) progression …
A new review surveys a broadening landscape of studies showing what’s known, and what remains to be found, about the therapeutic potential of non-invasive sensory, electrical or magnetic stimulation of gamma brain rhythms. A surprising MIT study published in Nature at the end of 2016 helped to spur interest in the possibility that light flickering at the frequency of …
In mice and human cell cultures, MIT researchers showed that novel nanoparticles can deliver a potential therapy for inflammation in the brain, a prominent symptom in Alzheimer’s disease Some Covid-19 vaccines safely and effectively used lipid nanoparticles (LNPs) to deliver messenger RNA to cells. A new MIT study shows that different nanoparticles could be used for a …
A new MIT study finds that microglia with mutant TREM2 protein reduce brain circuit connections, promote inflammation and contribute to Alzheimer’s pathology in other ways A rare but potent genetic mutation that alters a protein in the brain’s immune cells, known as microglia, can give people as much as a three-fold greater risk of developing …
By analyzing epigenomic and gene expression changes that occur in Alzheimer’s disease, researchers identify cellular pathways that could become new drug targets Alzheimer’s disease affects more than 6 million people in the United States, and there are very few FDA-approved treatments that can slow the progression of the disease. In hopes of discovering new targets …
