The Effects of Mild Disturbances on Sleep Behaviour in Laying Hens
The positive welfare of commercial animals presents many benefits, making the accurate assessment of welfare important. Assessments frequently use behaviour to determine welfare state; however, nighttime behaviours are often ignored.

Sleep-wake patterns and sleep quality in urban Georgia
Sleep problems represent a worldwide health concern but their prevalence and impacts are unknown in most non-European/North American countries. This study aimed to evaluate sleep-wake patterns, sleep quality and potential correlates of poor sleep in a ...

A Century Searching for the Neurons Necessary for Wakefulness
Wakefulness is necessary for consciousness, and impaired wakefulness is a symptom of many diseases. The neural circuits that maintain wakefulness remain incompletely understood, as do the mechanisms of impaired consciousness in many patients. In contrast

Detecting Brain Activity Following a Verbal Command in Patients With Disorders of Consciousness
BackgroundThe accurate assessment of patients with disorders of consciousness (DOC) is a challenge to most experienced clinicians. As a potential clinical tool, functional magnetic resonance imaging (fMRI) could detect residual awareness without the need

Decline of long-range temporal correlations in the human brain during sustained wakefulness [PDF]
Sleep is crucial for daytime functioning, cognitive performance and general well-being. These aspects of daily life are known to be impaired after extended wake, yet, the underlying neuronal correlates have been difficult to identify.

Arousal State-Dependent Alterations in Neural Activity in the Zebra Finch VTA/SNc
Sleep-wake behaviors are important for survival and highly conserved among animal species. A growing body of evidence indicates that the midbrain dopaminergic system is associated with sleep-wake regulation in mammals.

Dysfunctions of the paraventricular hypothalamic nucleus induce hypersomnia in mice
Hypersomnolence disorder (HD) is characterized by excessive sleep, which is a common sequela following stroke, infection, or tumorigenesis. HD is traditionally thought to be associated with lesions of wake-promoting nuclei.
