Sleep Helps the Brain to Memorize Facts
Research by scholars of Harvard University and Boston College, USA, showed that sleep influences the storage of facts, keeping or deleting memories, as they have emotional significance.
In practice, it was noted that a period of sleep helps the brain store memories in time to eliminate those more emotional and more neutral.
To check the impact of sleep in the selection of memory, the researchers divided the participants into three groups. The first went through a memory test during the day, but after 12 hours awake. The second group underwent the same test after 12 nighttime hours, which included the normal period of sleep. Since students in the third group underwent memory testing after 30 minutes that saw the scenes.
The results show that most students in the first group, who took the test after 12 hours awake, did not remember the downside of the images, as well as forgotten the neutral objects. Among students who were tested for memory after a sleep period, the majority of objects recalled negative. The accuracy of the details of this scene was the same as reported by students who have passed the half hour after seeing the images.
Scholars have concluded that the scene was most remembered emotional impact and, therefore, was prioritized by the brain during sleep. In addition to storing the best memories most important, students who have fallen asleep before the tests had not withheld many details about the neutral scenes. This demonstrates that the sleep aid in the selection of memories.
Stress and lack of nutrients affect memory
When the memory starts to fail repeatedly can be a sign that your brain needs more attention. Stress is one of the biggest agents that interfere with memory, because of cortisol, a hormone released in stressful situations, which interferes with the production of new neuronal cells, affecting memory.
Foods rich in B complex are mineral grains. They work in favor of cognitive function and are found in grains such as rice, rye, wheat germ, beans and fish. Guarana and cocoa are good allies in this task. But they need to be used in moderation, about one teaspoon per day.
Another fat essential for the proper functioning of the brain is the omega-3. He has an important role in brain development in children and maintains normal brain function in adults, he says. To find the fat, Doctors recommend cold-water fish such as sardines and salmon, and flaxseed.
