If you have a bad memory, it may be that the quality of sleep is also bad. Scientists through a study has found a link between a thing of the past with poor sleep quality found.
Research at UC Berkeley have discovered that the brain wave is low, and plays an important role in the storage, supply the goods stored in the hippocampus. This is the part of the brain which serves to maintain short-term memory.
Memory of the elderly are often caught in the hippocampus when you try to call you again. This is due to poor brain waves during sleep is not restful. The memory is erased and replaced by the new memory.
The researchers said their findings so dysfunctional that would help clarify the relationship between sleep disorders, brain damage and memory loss with age, which continues to grow.
During their growth, reduce the
quality of sleep
He also said that when a person is young , it is generally get enough sleep rations and rewarding to help the brain stores memories. However, during growth, the quality of sleep is reduced, which may prevent the memory storage in the night. A healthy adult will have a good night's sleep without fast a quarter of the night usually eye movements.
The study involved 18 subjects in good health aged between 20 and 15 years older than 70 healthy subjects. You need to sleep well the night before. At bedtime, we asked participants to remember 120 words. Meanwhile, when they sleep, are electroencephalogram ( elcetroencephalographic ) to monitor their brain activity. In the morning, they were asked to remember 120 words, but this time it was a machine of magnetic resonance imaging brain scans ( magnetic resonance imaging ) test.
A scan of the young participants showed when sleep has contributed to short-term memory in the hippocampus in long-term memory is stored in the prefrontal cortex. On the other hand, the participants who had an older age, it is known that the quality of their sleep 75 % lower compared to younger participants. Regarding the value of the word recall test, older participants receive a score lower than 55 percent.
