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

Pupil constriction during sleep may protect the murine brain from being awakened by sudden flashes of light.

Brain-derived neurotrophic factor affects onset and duration of REM in the animals, but not other phases of sleep.

The award in Physiology or Medicine goes to chronobiologists Jeffrey Hall, Michael Rosbash, and Michael Young.

Humans can remember new sensory information presented during REM sleep, but this ability is suppressed during deep, slow-wave slumber.

New methods could propel investigation of neural “PGO” wave patterns that may underlie critical aspects of visual experience, dreaming, and even psychosis.

When Caenorhabditis elegans surrenders to slumber, the majority of its neurons fall silent.

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

Scientists identify a mutation in the CRY1 gene in people with abnormal sleeping patterns.
