Falling asleep involuntarily during the day poses a very real and dangerous problem, Canadian researchers said. Researchers at the Montreal Neurological Institute at McGill University demonstrates sleep-wake states are regulated by two types of nerve cells, melanin-concentrating hormone neurons and orexin neurons, which occupy the same region of the brain, but perform opposite functions. The study is the first to discover that melanin-concentrating hormone neurons are activated during sleep...

Lack of sleep is a common complaint but for many, falling asleep involuntarily during the day poses a very real and dangerous problem. A new study from the Montreal Neurological Institute (MNI) at McGill University demonstrates interestingly, that sleep-wake states are regulated by two different types of nerve cells (neurons), melanin-concentrating hormone (MCH) neurons and orexin (Orx) neurons, which occupy the same region of the brain but perform opposite functions. The MNI study is the...

Mice with increased levels of a natural brain chemical don't gain weight when fed a high-fat diet, researchers at UT Southwestern Medical Center have found. The chemical, orexin, works by increasing the body's sensitivity to the "weight-loss hormone," leptin, the researchers report. Finding a way to boost the orexin system may prove useful as a therapy against obesity, said Dr. Masashi Yanagisawa, professor of molecular genetics at UT Southwestern and senior author of the study, which appears...

An unusual sleep disorder could be a precursor to dementia or Parkinson's disease. Patients with REM sleep behavior disorder have excessive muscle activity during REM sleep -- often called the dream stage of sleep -- causing them to punch, kick or cry out when they are in a deep sleep. Of the 93 REM sleep behavior patients involved in the study, 26 developed a neurodegenerative disease within five years. Doctors estimate the 10-year disease development risk to be 41 percent and the 12-year...

 People with a sleep disorder that causes them to kick or cry out during their sleep may be at greater risk of developing dementia or Parkinson's disease, according to a study published in the December 24, 2008, online issue of Neurology®, the medical journal of the American Academy of Neurology.The sleep disorder is called REM sleep behavior disorder. People with the disorder do not have the normal lack of muscle tone that occurs during REM sleep, often known as the...

In a novel study appearing this week in Neuron, Brandeis researchers identify for the first time a specific set of wake-promoting neurons in fruit flies that are analogous to cells in the much more complex sleep circuit in humans. The study demonstrates that in flies, as in mammals, the sleep circuit is intimately linked to the circadian clock and that the brain's strategies to govern sleep are evolutionarily ancient. In the study, researchers quieted ventral lateral neurons (LNvs) and...

Japanese scientists may have identified a gene variant linked to narcolepsy. Narcolepsy is a condition marked by excessive daytime sleepiness, impaired vision and muscle weakness. In the United States and Europe it occurs in 1 out of 2,500 individuals, but is at least 4 times more frequent in Japanese. The researchers wrote in a paper published in Nature Genetics that the genomes, or DNA, of 222 narcoleptic Japanese were analyzed as well as 389 others who did not have that condition, and one...
