Detects tremors of memory and memory

Human memory is finite, while the thing to remember is almost limitless. The question is how can our brain filter the information we need to keep?

Research in neuroscience

Scientists have long been studying the memory system based on theoretical models on hamsters, but recently, they have just discovered the system of memory feedback in humans.

A research team at Oxford University, led by Dr. Helen Barron - a neuroscientist - published the results of her research in the journal Neuron (Neuron). They believe that they have found the "antimatter" of the nervous system - the memory system in the human brain.

Human memory - at a fundamental level - is essentially a charge of electricity between neurons. When you establish a new memory, the relationship between these neurons is activated and becomes excited.

However, if the mechanism of storing information in the brain is only that, remembering new memories or learning something new can make the brain's electrical activity in the body become overloaded, leading to a number of conditions such as schizophrenia, autism and seizures.

Therefore, according to the theory of Oxford University researchers, there must be a system to inhibit the activity of neurons, bringing electromagnetic activity in the brain to equilibrium. These are essentially neuron bonds that generate electrical impulses in contrast to the electrical impulses generated when neurons connect to remember new information. They named this system a memory-feedback system.

According to scientists, this mechanism does not affect memory, but only works to prevent the brain from reading information stored in the memory domain . "The role of the memorization system is not to support forgetting but to support the storage process of memory, allowing you to save a lot of memories without fear of being mixed together. For example. If you try to remember the last time you saw your mother, you won't want to remember all the times you saw your mother before, " said Dr. Barron.

Dr. Helen Barron said that more research is needed to find out the mechanism of memory recollection, including the mutual relationship between memory system and memory.

Opportunities for people with brain diseases

To draw conclusions about the role of anti-memory, scientists have conducted a special experiment. Volunteers participating in the experiment were instructed to combine cubes with different colors. Meanwhile, researchers use functional magnetic resonance imaging (fMRI) to see how the volunteer brain works.

This research model can be applied directly to patients.

They found that after more than 24 hours, the brain's cubic combination did not show up when volunteers were shown the picture again. Researchers have used a technique to stimulate direct lowering of the brain through the brain to prevent the concentration of nerve chemicals, including gaba - a substance directly related to inhibition. In this way, they reduced the activity of memory-inhibiting neurons, helping to restore information about the cubic combination of volunteers.

"We have shown that, the reduction in inhibition in cerebral cortex can help to recollect part of the memory. This result is consistent with the equilibrium mechanism of the brain: When the brain learns and remembers communication New news, that is when stimulating connections are strengthened, at the same time, inhibitory links are enhanced to balance brain activity, "said Dr. Helen Barron.

Although research has been conducted on a small scale, the results of Dr. Barron and his colleagues are opening new hopes for the treatment of neurological problems.

"This research model can be applied directly to patients - including people with schizophrenia and autism. We hope that this study will be of interest to physicians. gods and patients pay attention so we can develop and apply it to the analysis and treatment of mental disorders " - Ms. Barron said.
