After 180 years, new clues are revealing just how general anesthesia works in the brain
by Adam D Hines, The Conversation MAY 18, 2024 Credit: CC0 Public Domain Over 350 million surgeries are performed globally each year. For most of us, it’s likely at some point in our lives we’ll have to undergo a procedure that needs general anesthesia. Even though it is one of the safest medical practices, we...

Dancing cells show how the brain awakens from anesthesia
by Alison Satake, Mayo Clinic Neuronal hyperactivity occurs during emergence from general anesthesia. Credit: Nature Neuroscience (2024). DOI: 10.1038/s41593-023-01537-8According to a Mayo Clinic study published in Nature Neuroscience, the cells that act as the central nervous system’s first line of defense against harm also play a role in helping the brain awaken from anesthesia. This discovery...

Neurons help flush waste out of brain during sleep
Findings could lead to new approaches for Alzheimer’s, other neurological conditions by Marta Wegorzewska GETTY IMAGESResearchers at Washington University School of Medicine in St. Louis have found that brain cell activity during sleep is responsible for propelling fluid into, through and out of the brain, cleaning it of debris. There lies a paradox in sleep....
