‘Artificial sap’ could give the benefits of sleep without sleep
The monkeys’ brain despite the electricity caused performance to encourage performance
What will happen we can get the benefits of the memory, learning and perception of “Power Naps” without sleeping?
A recent study in Science It suggests at least some of our primous cousins. Researchers showed some short maps (without Quick eye movement, or REM, sleep) Macaques’ improve performance in visual perception tasks. Scientists then reproduce this impulse by stimulating the brains of the wonderful monkeys, mimetic brain activities to sleep “causing a kind of artificial nap”. Processes, if effective in humans, one day helps to help promote cognition and treat sleep problems.
The team first trained five monkeys to evaluate the orientations of the images and tested them twice, which had a 30-minute gap, yes, they do not sleep or rest. The monkeys slept were significantly improved in the second test. Researchers recorded thousands of neurons activities in the three brain regions: two visual sites and a decision-making. In the monkeys who slept between the tests, this activity was curious in secondary tasks than the first.

“Sleep is a synchronous phenomenon after climbing and sleeping together, but after sleeping, the level of synchronization has been reduced,” The main study of the study, the system with neuroscience of rice college. “It’s amazing.” The size of this “desynchronizer” operation increases.
Low frequency “Delta” brain waves are involved in memory maintenance. These waves dominated the brain activities of the monkeys, and the team asked if they were behind the sculpting of the performance. To test, researchers did an experiment again, but instead of sleeping monkeys, he stimulated the visual brain region using Mimiced Delta waves using electricity electricity. This stimulation also brought a reduced neuralronous and better performance.
These findings should not deliver the benefits of NAPS without sleep without sleep. The results of primates will return to humans “artificial” effects, Sara Mednick, in the Neuroscience of California, studies the relationship between nappine and performance; There are already evidence that electrical stimulation can benefit from human memory. “This work shows that stimulation of delta frequency (when it wakes up) imitates sleep benefits,” Mednick said.
Researchers used electrodes located in monkey brains for stimulation, but they intend to test non-invasive techniques in people with sleep disorders, “In the near future, Dragon says. In addition, the other senses, cognitive functions and the brain regions, has added. “Are the most special tasks different areas? No one knows.”
