U.S. scientists discover for the first time the mechanism of dynamic connections in the human brain

Scientists at the Center for The Basic Research Center for Neurocognitive Research in the United States,, say they have successfully discovered the mechanism of "dynamic connections" in the human brainIn a "dynamic" state of the brain, neural networks can be quickly connected to feel and recognize external stimuli more keenlyThe Center for the Basic Research Center for Neurocognition is a joint venture between Carnegie Mellon University and the University of PittsburghThe researchers say their analysis of the work of the human brain will help explain, for example, why people notice a smell, and the brain can quickly determine what substance the smell comes from"If you look at the brain as if it were the same computer, the connection between neurons is the brain's operation software," said study leader Nathan Erben, an associate professor of biology at Carnegie Mellon UniversityOur research shows that biological software is like a function, changing rapidly as the amount of input the system receives"
when people encounter external stimuli such as smell, many neurons start to signalBut it's not a good thing that many neurons signal at the same time, because it makes it difficult for the brain to explain exactly what causes the phenomenonAt this point, the brain produces lateral inhibitions, in which the stimulated neurons send a message to neighboring neurons that stop signalling, reducing background noise and allowing the brain to easily and accurately identify external stimuliIn the course of the study, Erben and colleagues focused on the process of lateral inhibition in the brain's olfactory ballsThey found that, in fact, neuronal connections were not pre-set, but were dynamically changing in response to special patterns of external stimuliIn the experiment, they learned that when excited neurons in the olfactory ball signal edited in a related way, they determined a functional connectionThe researchers believe that when a large number of neurons react to external stimuli, dynamic connections strengthen lateral inhibition, filtering out background noise from other neuronsAs a result, the brain can identify stimuli more clearly and distinguish them from other similar stimuli Mr Erben says the dynamic connection mechanism explains why people can tell the smell of flowers as soon as they enter the room And as he continued to smell, he could confirm that it was the smell of flowers, and even more accurately known the smell of roses Erben also believes that by understanding the brain's behavior, people can apply this mechanism to other problems facing the human brain
