New research shows that neurons in the preoptic hypothalamus – the region of the brain that regulates sleep and body temperature – are rhythmically activated during non-rapid eye movement (NREM) sleep. According to a study published in Current Biology from the Perelman School of Medicine at the University of Pennsylvania, stress activates these brain cells uncontrollably, […]
Obesity is defined as having a body mass index (BMI) of 30 or more. Being overweight or obese increases the risk of health problems such as high blood pressure and type 2 diabetes. Schedules and individual sleep, eating and exercise rhythms can also impact health by either complementing or contradicting the body’s natural circadian rhythm. […]
New research from a multidisciplinary team is helping to shed light on the mechanisms behind circadian rhythms and offer new hope for dealing with jet lag, insomnia and other sleep disorders. Using innovative cryo-electron microscopy techniques, researchers have identified the structure of the circadian rhythm photosensor and its target in fruit flies (Drosophila melanogaster), one […]
Alzheimer’s disease begins when plaques of the protein amyloid beta build up in the brain. After years of amyloid accumulation, a second brain protein, tau, begins to form tangles that are toxic to neurons. People with Alzheimer’s begin to experience cognitive symptoms, such as memory loss, around the time tau involvement is detectable. The brain […]
Both cluster headaches and migraines have strong connections to the circadian system, the internal clock that regulates body processes, according to a meta-analysis published March 29, 2023 in the online edition of Neurology®, the medical journal of the American Academy of Neurology. Cluster Headache More Severe in Women Cluster headache is a rare headache disorder, […]
