Older brains may forget more because they lose their rhythm at night. During deep sleep, older people have less coordination between two brain waves that are important to saving new memories, a team reports in the journal Neuron. “It’s like a drummer that’s perhaps just one beat off the rhythm,” says Matt Walker, one of the paper’s authors and a professor of neuroscience and psychology at the University of California, Berkeley. “The aging brain just doesn’t seem to be able to synchronize its brain waves effectively.” (Hamilton, 12/18)
