Researchers have created a new model that may help explain how different sleep patterns may help us to solve problems. The study reveals non-REM sleep helps us categorize information, where as REM sleep helps us to draw unexpected connections between information we have been exposed to.
Researchers have identified a second gene that contributes to natural short sleep. Using optogenetics, researchers triggered neurons in the pons that express the ADRB1 gene, rousing mice from sleep. Wakefulness-promoting neurons in the pons with a mutated version of ADRB1 were more easily activated.
Researchers identify a neural circuit in the brain that helps regulate REM sleep.
According to a new study, the consequence of daily stress is linked to an increase in REM sleep. Researchers report the increase is associated with genes involved in apoptosis and cell survival. The findings shed light on how stress leads to mood disorders, and how changes in sleep contribute to this.
Monitoring sleep spindles in sheep may one day translate to sleep based diagnosis of neurodegenerative diseases in humans.
Researchers discover a link between neural activity in the lateral hypothalamus and the state of REM sleep.
Researchers report dream dysfunctions and sleep disorders may be warning signs of neurodegenerative diseases up to 15 years before other symptoms appear.
Dreams that appear to be simultaneously realistic and bizarre help our brains learn and extract generic concepts from previous experiences, a new study reports.
REM sleep behavior disorder, or parasomnia, affects more than 80 million people worldwide. The disorder causes sufferers to experience nightmare-like violent dreams. Sufferers act on their dreams while sleeping, often resulting in violent or dangerous sleep behaviors and injuries. Researchers propose new guidelines, including medical and pharmacological recommendations, to help curb symptoms of parasomnia and promote healthier sleep.
Researchers at Johns Hopkins have identified specific neurons in the zona incerta that appear to help promote sleep. The discovery could help develop new treatments for insomnia and other sleep disorders.
Researchers at Northwestern University report older adults who suffer from sleep disturbances such as sleep apnea and restless leg syndrome might enjoy a better night's sleep by cultivating a purpose in life.
A simple actimeter device is helping researchers better understand sleep duration and quality in humans.
