Adult born neurons are essential for synaptic structural remodeling and memory consolidation during REM sleep, a new mouse study found.
Adults who share a bed with their partners sleep better than those who sleep alone. Researchers found bed-sharing was associated with a lower risk of depression and stress, and improved quality of life and relationships. However, sharing a bed with a child was associated with more stress.
New, advanced EEG technology allows researchers to easily visualize brain activity during sleep.
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.
Following a 12 year long study, researchers have identified seven phenoclasses that can help doctors to diagnose and track the progression of bipolar disorder in patients.
An afternoon nap may help improve mental agility, a new study suggests. A short afternoon nap was associated with better working memory, verbal fluency, and locational awareness.
Sleep efficiency dips for most around age 40, increasing again at around age 50. Researchers say that for most aged 60 and older, sleep duration increases.
A new machine learning study has revealed a novel combination of factors that can increase a person's risk of developing dementia.
New machine learning technology that researchers have made free online can be used by sleep experts to study the role of K-complex, a brief but prominent pattern of brain activity that lasts around half a second during sleep.
Artificial intelligence technology redesigned a bacterial protein that helps researchers track serotonin in the brain in real time.
A new study suggests air pollution could be a reason for sleep disruptions.
Tau accumulations disrupt wake-promoting neurons. The findings help explain why day-time napping and sleep disruptions are often reported in Alzheimer's patients.
