Incomplete sleep affects the ability to remember and store memories, according to a study at Stanford University.
The discovery may be useful for understanding memory problems, as seen in diseases such as Alzheimer's disease and sleep apnea.
Another 1960 study showed that people who do not sleep enough, have memory problems.
In a state of deep sleep the brain processes and stores data and information onevents in the past day.
According to recent research on the brain during sleep consolidates originally"fragile" memories and process them for long term storage. In this process thehippocampus plays an essential role.
Conducive to sleep and improves the brain's ability to memorize declarative andprocedural information. Declarative memory is responsible for remembering facts and meaning of actions and events, and procedural memory - refers to action inunfamiliar situations.
Hippocampus is responsible for declarative memory. Different region of the braininvolved in processing of procedural information.
The new study investigated the fragmented sleep, but not shorter or less intense thannormal for the participants.
Dream of volunteers deliberately violated by the research team through optogenetikamethod. In the method used volunteers understand and realize that their sleep isdisturbed, is not affected and the total time of sleep.
The next day participants harder than ever displaying to recognize objects falling asleep, which means that their memories are concerned, are clear from the scientificteam.
Quality of sleep is one of the main factors associated with various pathological conditions that affect memory, including Alzheimer's disease and other age-relatedcognitive deficits.
Fragmented sleep affects people dependent on alcohol, and those with sleep apnea- a condition occasionally stop breathing for seconds during sleep.
