Sufficient restful sleep leads to improved cognitive function and also enhanced memory formation, while insufficient, restless sleep has harmful effects such as impaired memory and judgment, and can lead to increased risk for medical conditions such as stroke, obesity, and cardiovascular disease.
According to new findings:
- MicroRNA expression may serve as an indicator of sleep loss in rats and humans, suggesting a possible method for predicting those at risk for diseases and cognitive deficits typically associated with sleep debt (Seema Bhatnaghar).
- Three species of spiders have amazingly fast circadian clocks, raising questions about how they avoid the negative effects typically associated with deviating from the normal biological timeframe (Darrell Moore).
Other findings discussed explain that:
- A computerized algorithm can determine whether people viewed images of faces or houses by comparing patterns of electrical activity in the brain during sleep (Monika Schonauer, abstract 193.09, see attached summary).
"Sleep is even more multifaceted and fascinating than we realize," said press conference moderator Sigrid Veasey, a professor at the Center for Sleep and Circadian Neurobiology at the University of Pennsylvania's Perelman School of Medicine.
The research was supported by the national funding agencies such as the National Institutes of Health, as well as other public, private, and philanthropic organizations worldwide.
The studies were presented at Neuroscience 2017, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health. (ANI)
