Sleep in Fish Models

The origins and evolution of sleep

TLDR
The contributions of classical and emergent genetic model systems to investigate mechanisms underlying sleep regulation are described, highlighting fundamental interactions between sleep and sensory processing, as well as a remarkable plasticity of sleep in response to environmental changes.

The Regulation of Drosophila Sleep

The Birth of the Mammalian Sleep

TLDR
It is concluded that the main function of sleep consists in guaranteeing it during a part of the daily cycle, including homeostatic regulation, as well as the high variability in sleeping patterns observed today.

Neurotransmitters of sleep and wakefulness in flatworms

TLDR
The potential of neurotransmitters to regulate sleep and wakefulness in flatworms is demonstrated and the conserved action of some neurotransmiters across species is highlighted.

Neuronal Mechanisms for Sleep/Wake Regulation and Modulatory Drive

TLDR
This review discusses electrophysiological and behavioral features of sleep/wake states and the principal neuronal populations involved in their regulation, and describes the main modulatory drives of sleep and wakefulness, including homeostatic, circadian, and motivational processes.

Unique transcriptional signatures of sleep loss across independently evolved cavefish populations

TLDR
The behavioral and molecular response to sleep deprivation across four independent populations of A. mexicanus is examined, suggesting sleep homeostasis is intact in cavefish despite a dramatic reduction in overall sleep duration.

The neural architecture of sleep regulation – insights from Drosophila

TLDR
It is illustrated that neural networks require sleep to undergo synaptic reorganization that allows for the incorporation of experiences made during the waking hours, and that the basic functions and physiological principles of sleep are highly conserved throughout the phylogenetic spectrum.

Adaptation and survival: hypotheses about the neural mechanisms of unihemispheric sleep

TLDR
The aims of this article are to formulate hypotheses about the neural mechanisms of unihemispheric sleep(US) based on findings regarding the Neural mechanisms of the sleep/wake cycle of mammals.

Clues to the functions of mammalian sleep

The functions of mammalian sleep remain unclear. Most theories suggest a role for non-rapid eye movement (NREM) sleep in energy conservation and in nervous system recuperation. Theories of REM sleep

Phylogenetic Analysis of The Ecology and Evolution of Mammalian Sleep

TLDR
It is found that basal metabolic rate correlates negatively rather than positively with sleep quotas, and that neither adult nor neonatal brain mass correlates positively with REM or NREM sleep times, which contradict hypotheses that invoke energy conservation, cognition, and development as drivers of sleep variation.

Sleep has been observed in all vertebrates studied and in several invertebrates, notably the fruit fly Drosophila melanogaster. In all species, a substantial portion of life is spent in this

The Neurobiology of Sleep: Genetics, cellular physiology and subcortical networks

To appreciate the neural underpinnings of sleep, it is important to view this universal mammalian behaviour at multiple levels of its biological organization. Molecularly, the circadian rhythm of

A Phylogenetic Analysis of Sleep Architecture in Mammals: The Integration of Anatomy, Physiology, and Ecology

TLDR
It is found that species with higher relative BMRs engage in less SWS, whereas species with larger relative brain masses engage in more REM sleep, and REM sleep was the only sleep variable strongly influenced by predation risk.

Sleep in Drosophila is regulated by adult mushroom bodies

TLDR
It is shown that large changes in sleep are achieved by spatial and temporal enhancement of cyclic-AMP-dependent protein kinase activity specifically in the adult mushroom bodies of Drosophila, which links sleep regulation to an anatomical locus known to be involved in learning and memory.

Adaptive Sleep Loss in Polygynous Pectoral Sandpipers

TLDR
It is shown that male pectoral sandpipers (Calidris melanotos), a polygynous Arctic breeding shorebird, are able to maintain high neurobehavioral performance despite greatly reducing their time spent sleeping during a 3-week period of intense male-male competition for access to fertile females.

Cetacean sleep: An unusual form of mammalian sleep

Widespread Changes in Synaptic Markers as a Function of Sleep and Wakefulness in Drosophila

TLDR
Using Western blots and confocal microscopy in Drosophila, it is found that protein levels of key components of central synapses were high after waking and low after sleep, and sleep may be involved in maintaining synaptic homeostasis altered by waking activities.
