Researchers are experimenting with a variety of tools, from brain stimulation to audiovisual equipment, to try to take control of the sleeping brain.

Meet some of the people featured in the December 2020 issue of The Scientist.

In mice, the brain’s main glial cell type exhibits distinctive patterns of activity across the sleep-wake cycle and influences the response to sleep deprivation.

During deep sleep, rhythmic pulses of cerebrospinal fluid are coupled with slow waves of electrical activity and fluctuating blood levels in the human brain.

Neurons can only efficiently fix genetic injuries when the animals are asleep.

Sleeping on a rhythmically swaying surface helps synchronize sleep oscillations in the human brain, a study finds.

People who have suffered traumatic brain injury had slower reaction times and more false starts after disrupted sleep than healthy controls, according to a study presented at the Society for Neuroscience meeting.

Two studies identify a signaling pathway that contributes to the fish’s sleeplessness.

By examining brainwave patterns in a posterior cortical area, scientists can predict when people are dreaming.
