What's up in
By digging out signals hidden within the brain’s electrical chatter, scientists are getting new insights into sleep, aging and more.
An organized tide of brain waves, blood and spinal fluid pulsing through a sleeping brain may flush away neural toxins that cause Alzheimer’s and other diseases.
While we sleep, one kind of slow brain wave helps to reinforce memories, but a competing wave weakens them.
The identification of SNIPPs, a set of proteins found primarily at the brain’s synapses, brings science closer to understanding why we need to sleep.
