Astrocytes could be as important as neurons when it comes to regulating sleep.
Researchers identified molecules that can modulate circadian rhythms by binding to the MT1 melatonin receptor in the hypothalamus.
Galanin expressing neurons are selectively active during rebound sleep. The expression of galanin increases after neuronal activity and sleep deprivation. The neuropeptide plays a critical role in sleep homeostasis.
Study adds to a growing body of evidence that stress in the workplace, coupled with impaired sleep, increases the risk of cardiovascular disease and coronary mortality, especially in hypersensitive workers.
A link has been identified between oxidative stress, which has previously been linked to aging and neurodegeneration, and sleep. Oxidative stress activates neurons that control sleep function. The findings could help in the development of treatments for sleep disorders.
Autoreactive cytotoxic CD8 T cells have been detected in people with narcolepsy type one. The finding suggests levels of the T-cell reactivity, combined with specific gene expression, may spur on the development of NT1.
Researchers have identified five different subtypes of the sleep disorder insomnia, including difficulty falling asleep and early morning awakening. The study reports insomnia subtypes may be identified by examining personality traits of sufferers.
Using new technology to turn inflammation on and off in mice, researchers discover inflammation may contribute to sleep disorders.
People who suffer from REM sleep behavior disorder are at increased risk of developing Parkinson's disease and dementia as they age, a new study reports. Researchers report RBD causes a lack of dopamine in the brain, and this can contribute to the development of neurodegenerative diseases.
MIT researchers have developed a new, non invasive method to help monitor sleep patterns. The device uses an advanced AI algorithm to analyze wireless signals around a person and translate the measurements into sleep stages. Researchers plan to use the technology to study how Parkinson's disease affects sleep.
Researchers report dream dysfunctions and sleep disorders may be warning signs of neurodegenerative diseases up to 15 years before other symptoms appear.
