This result remained when controlling for sleep duration, which suggests that sleep variability may be more consequential for teen brain development than simply duration. Another study found that sleep duration was strongly associated with gray matter volume of the bilateral hippocampus among a sample of healthy children and adolescents. [20]
The subjects who engaged in REM sleep performed significantly better, indicating that REM sleep facilitated the consolidation of nondeclarative memories. [7] A more recent study [ 16 ] demonstrated that a procedural task was learned and retained better if it was encountered immediately before going to sleep, while a declarative task was learned ...
A new study has found sleep deprivation in kids in elementary school can affect brain structure and have lasting effects on school performance, mental health. New Study Reveals Lack of Sleep Can ...
Sleep deprivation also has a documented effect on the ability to acquire new memories for subsequent consolidation. A study done on mice that were sleep deprived before learning a new skill but allowed to rest afterward displayed a similar number of errors on later trials as the mice that were sleep deprived only after the initial learning.

Sleep has been shown to have a long list of physical and mental health benefits, and now a new study suggests it could also help to “erase" bad memories. Experts comment on the findings.
A genetic predisposition for insomnia has been found among some children, a new study found. But there are still actions you can take to help your kids, experts said.
Another potential purpose for sleep could be to restore signal strength in synapses that are activated while awake to a "baseline" level, weakening unnecessary connections that to better facilitate learning and memory functions again the next day; this means the brain is forgetting some of the things we learn each day.

A new study offers an explanation as to how deep sleep — also known as slow wave sleep — helps support the formation of memories in the brain, which could help with preventing dementia ...
