Sleep is an essential biological phase of our daily life cycle and is necessary for maintaining
homeostasis, alertness, metabolism, cognition, and other key functions across the animal …

The immature brain spontaneously expresses unique patterns of electrical activity that are
believed to contribute to the development of neuronal networks. Certain electrographic …

Despite the predominance of sleep in early infancy, developmental science has yet to play a
major role in shaping concepts and theories about sleep and its associated ultradian and …

Abstract Study Objectives In adults, wakefulness can be markedly prolonged at the expense
of sleep, eg to stay vigilant in the presence of a stressor. These extra-long wake bouts result …

Zebrafish (Danio rerio) are used extensively in sleep research; both to further understanding
of sleep in general and also as a model of human sleep. To date, sleep studies have been …

Abstract Study Objective: Upon awakening from sleep, a fully awake brain state is not
reestablished immediately, but the origin and physiological properties of the distinct brain …

We analyzed the effects of dopamine signaling on the temporal organization of rest and
activity in Drosophila melanogaster. Locomotor behaviors were recorded using a video …

Sleep behavior is present in nearly all animals, and is a vital part of growth, development,
and overall health. Infant mammals cycle randomly between short bouts of sleep and wake …

In early infancy, rats randomly alternate between the sleeping and waking states–from
postnatal day 2–10 (P2-P10), sleep and wake bouts are both exponentially distributed with …

The mammalian locus coeruleus (LC) is a brainstem structure that displays extensive
interconnections with numerous brain regions, and in particular plays a prominent role in the …
