In a study published online April 18 in Neuron, researchers found that general anesthesia induces unconsciousness by hijacking the neural circuitry that makes us fall sleep. They traced this neural circuitry back to a cluster of cells at the base of the brain responsible for churning out hormones to regulate bodily functions, mood, and sleep. The finding could lead to better drugs capable of putting people to sleep with fewer side effects.
A new Canadian study of more than 2,400 families suggests that among preschoolers, spending two hours or more of screen time per day is linked to clinically significant behavioural problems.
Researchers have identified a pattern of brain activity that reflects anger experienced during dreaming according to a new study carried out on healthy adults and published in The Journal of Neuroscience. The study helps to clarify the neural basis of dream emotions.
Researchers measured a novel treatment for sleep apnea developed at Hiroshima University Hospital with positive results. By measuring patients lying down flat, the researchers stimulated sleep conditions and measured the patient's airways using 3D imaging. The study confirmed that the treatment is effective at opening the airways and warrants further collaboration between dentists and doctors in treatment of sleep apnea.
People often say they can get by on five or fewer hours of sleep, that snoring is harmless, and that having a drink helps you to fall asleep. These are, in fact, among the most widely held myths about sleeping that not only shape poor habits, but may also pose a significant public health threat.
Researchers have identified a pattern of brain activity that predicts anger experienced during dreaming, according to a new study of healthy adults published in JNeurosci. The research could potentially inform efforts to understand the neural basis of the emotional content of nightmares, a feature of various mental and sleep disorders.
A new study by University of Guelph researchers explains why heart failure patients often have trouble with thinking and depression, pointing to ways to prevent and treat both heart and brain maladies through the emerging field of circadian medicine.
The largest genetic study of its kind ever to use accelerometer data to examine how we slumber has uncovered a number of parts of our genetic code that could be responsible for causing poor sleep quality and duration.
In a Geriatrics & Gerontology International study of 752 older adults with hypertension followed from 2008-2010 through 2012-2013, using sleeping pills on a regular basis was linked with use of an increasing number of blood pressure medications over time.
In a Child Development study of daily diary descriptions of discrimination by minority adolescents, experiencing discrimination during the day was associated with compromised sleep quality that night, as well as feelings of greater daytime dysfunction and sleepiness the following day.
