Adrian Owen and Karnig Kazazian use brain activity patterns to predict survival rates of ICU patientsBy Jeff Renaud,July 22, 2024 (L to R) Adrian Owen and Karnig Kazazian combine different neuroimaging methods to assess patients at the bedside in the first few days after their brain injury. (Christopher Kindratsky/Western Communications) The very thought of being...
by Laurel Hamers, University of Oregon An often-overlooked communication strategy for neurons might be more prevalent than previously believed. New research from biology professor Adam Miller’s lab in the UO’s College of Arts and Sciences illuminates the importance of neuron-to-neuron communication via direct electrical signaling, instead of the usual chemical messengers sent between cells. The team...
by Caroline Sheedy, Carnegie Mellon University Credit: Pixabay/CC0 Public Domain In a paper published in Neuron, Aryn Gittis and colleagues present new information about a neural pathway in the basal ganglia, a part of the brain important for skill learning, habit formation and motor control. The paper contradicts the model that has guided researchers’ understanding of motor...
by James Devitt, New York University Credit: public domain The size of our primary visual cortex and the amount of brain tissue we have dedicated to processing visual information at certain locations of visual space can predict how well we can see, a team of neuroscientists has discovered. Its study, which appears in the journal Nature Communications,...

Sarah Scoles January 21, 2020 Some of the hearing loss we’ve blamed on age might be due to how many fire trucks we’ve stood next to. But there are still ways to diagnose—and protect—against that environmental damage.Anthony Gerace Tucked inside the air traffic control tower in Portland, Maine, Samantha Bassett was busy making sure planes didn’t...
When the brain forms a memory of a new experience, neurons called engram cells to encode the details of the memory and are later reactivated whenever we recall it. A new MIT study reveals that this process is controlled by large-scale remodeling of cells’ chromatin. This remodeling, which allows specific genes involved in storing memories...
