We all lose brain cells as we get older. In people with neurodegenerative diseases such as Alzheimer’s, Parkinson’s and Huntington’s, neurons shrivel and die at alarming rates—perhaps three to four times faster than usual in Alzheimer’s, for example. Currently, no known drugs reliably halt or reverse such staggering cell death in people, although some drugs [...]

The Brainwave That Lets You Recognize What’s New in the World

A gamma wave is a rapid, electrical oscillation in the brain. A scan of the academic literature shows that gamma waves may be involved with learning memory and attention—and, when perturbed, may play a part in schizophrenia, epilepsy Alzheimer’s, autism and ADHD. Quite a list and one of the reasons that these brainwaves, cycling at [...]
