Electrical brain stimulation during sleep can help increase memory

For the first time, scientists say using alternating current to stimulate the brain, can create a specific type of brain activity during sleep that enhances human memory.

When you sleep, your brain is busy storing and rearranging what you spent that day, cramming the things you need into memory for tomorrow, next week or next year. For many people, especially those with impaired mental or memory conditions, this memory loss symptom will seriously affect daily life.

For the first time, scientists from the University of North Carolina School of Medicine said that the use of alternating current to stimulate through the skull has created a characteristic type of brain activity throughout sleep and helps boost the mind. Remember for people.

This finding, published in Current Biology, offers a non-invasive method that can help millions of people with autism, Alzheimer’s disease, schizophrenia and depression serious.

For years, researchers have recorded brain activity during sleep. These activities manifest in the form of electroencephalograms. These waves are called brain waves, and scientists have suspected their relevance in cataloging memories and storing memories when we sleep.

Dr. Flavio Frohlich, Professor Assistant Professor of Psychiatry and a member of the University of North Carolina’s Neurological Center, said: “In the past we did not know whether brain waves can make memories.

Whether or not they are stored or fortified or they are merely a by-product of other brain activity that allows us to store what we have experienced as a memory. points out that indeed, brain waves are an important process for creating memories that we need for everyday life, and we have used this result to enhance memory. “

This is the first time a research group has reportedly selected the goal of targeting brain waves without the increase in other natural brain activity during sleep. What has not been possible until now is using a stimulating DC current through the skull.
