What do we know about how the brain works?It is usually presented as a biological computer, which consists of many nerve cells. The brain is also a bit of a time machine. It consists of different sections, with each group of cells responsible for certain functions - memory, orientation in space, vision, hearing, emotions, etc. Cells exchange information with each other using synapses. According to this model, the activity of each neuron depends on the signals they receive from other neurons. That is, if a neuron receives a signal, it either sends an impulse to another neuron, or does not react to it in any way. However, according to a new study conducted by American scientists, there is another way the brain processes information - through the interaction of microwaves.
Scientists have found that the brain can use waves to process information
Does the brain process information in two ways?
Research results that can befound in Science Advances, allow scientists to better understand how the brain processes information. The traditional model of the brain can explain many processes, but not all. In particular, it cannot explain why a sensory cell is capable of responding differently to identical stimuli under different conditions.
For example, visual neurons are capable ofrespond to a flash of light, but only if the brain is focused on it. But, if attention is focused on something else, the same neurons will ignore exactly the same flash. The easiest way to explain this behavior, the scientists say, is to assume interacting microwaves.
According to the traditional model, neurons exchange impulses to process information.
But this way of processing information is not at allcontradicts the traditional model, which implies the exchange of impulses between brain neurons. Scientists compare the work of the brain with corpuscular-wave dualism, when quantum particles in some conditions have the properties of particles, and in others - the properties of waves. Perhaps the brain also uses different ways of processing information in different conditions.
How the brain processes information in a microwave way
In their work, scientists observed the activityneural network of the mammalian brain. It included 139 neurons. The aim of this study was to better understand how cells are able to respond to visual stimuli. As a result, the scientists found that the flash of light activated more than just certain sensory cells. The impulses were large-scale, that is, they covered the entire network. Moreover, they were distributed in such a way that something like a wave with alternating peaks arose.
To make it clearer, we are not talking about alpha at all,beta or gamma waves, which doctors observe during electroencephalography. These waves allow us to analyze the overall picture of the brain. The impulses that have been recorded in neural networks are microwaves.
The brain, depending on the situation, can process information in one of two ways.
When waves appear simultaneously in differentareas of the brain, they necessarily collide with each other. If two peaks of activity meet, more activity occurs. And if there is a peak of low activity with a peak of high activity, then the waves are neutralized. This process is called wave interference.

Why can our perception of the world change?
To find out how true the wave theory isinformation processing, the team conducted a visual experiment. Volunteers were asked to find a dimly lit line on a screen surrounded by various patterns of light. As it turned out, the ability of people to quickly find the line depended on several visual factors. This result of the experiment fully confirms the conclusions made by scientists.
“When you interact with the world, a personreceives a lot of input. Therefore, many waves arise simultaneously in the brain. The reaction of the brain to what is happening is connected with the interaction of these waves with each other, ”says Thomas Albright, one of the authors of the study.
According to scientists, waves arise andinteract with each other not only in the part of the brain that is associated with the processing of visual information, but in all parts of the cerebral cortex. For this reason, the waves that the brain itself generates are able to influence the waves that form sensory inputs. This may explain why the brain's response to something can be different on different days. You may not know, but the brain works differently even at different times of the year.
