Scientists at the Weizmann Institute of Science recently questioned the meaning attributed to findings that supported a leading theory, which many scientists considered an important step in deciphering the workings of the brain. Dr. Ilan Lampel from the Department of Neurobiology at the Weizmann Institute of Science, performed new experiments that led him to conclusions that may affect the direction of research designed to decipher the way information is coded in the brain. His findings were recently published in the scientific journal Neuron.
Information is transmitted in the brain through electrical signals between nerve cells. Today we are far from understanding how this information is represented in the brain and how it is processed in a way that allows understanding and recognition of the external environment. According to one of the accepted theories, different objects are represented through different patterns of electrical activity in time, so that the brain is able to differentiate between a chair and a table because each of them produces a different pattern of activity that is then translated by the brain. Therefore, when the same object is presented a second time, the representation pattern corresponding to it repeats a second time and is produced in a precise and controlled manner.
The members of the research group headed by Dr. Lampel asked to re-examine the findings that support this theory. They recorded the activity of the neurons in the upper layer of the brain in anesthetized rats, and analyzed the results with statistical tools they developed for this purpose. According to the analysis of the findings, it was found that the number of repeating patterns and the time needed to repeat them is completely coincidental. The scientists concluded that these patterns are not created in a controlled and deliberate manner, as it appeared from previous studies, and that in fact, they are created randomly.
This study contributes to the ongoing debate in the scientific community as to how information is encoded in the brain. Dr. Lampel: "Since the 80s of the last century, many researchers believed that they had the key principle to understanding the workings of the brain. But during only three years, we found significant evidence that the reappearance of precise activity patterns is coincidental and therefore the question of how the information is encoded in the brain remains open."

I got confused
Sir point. I recommend you read the brain explosion there are amazing things that you sure don't know. In one of the pages, the researchers stated that the number of ways of thinking is greater than the number of atoms in the entire universe. Do you know how many atoms there are in the entire universe? Do you know how many ways you can think of a math problem, thousands maybe hundreds! Did you know that boys only use one side of their brain to learn and think and when you see with your left eye then the right side of your brain causes it? There are things when you read them you will become the brain of the class and more than that.
It is not clear what the connection is between repetitive brain activity patterns in anesthetized rats and the question of whether brain activity patterns are typical for seeing certain objects.
Since each arrangement will have to include at least two atoms to form a continuous line, the number of atoms is greater.
Fan. The number of degrees to arrange all the atoms in the world is equal to the number of ways of thinking and is much greater
Sorry for my typos I'm only 12 years old
Do synapses have anything to do with these electrical waves? And did you know that the number of ways of thinking is greater than the number of atoms in the entire universe. The brain is perhaps one of the most complex things in the universe. is found in the back part of the brain when you get older the sense of taste weakens why do millions of brain cells die every day there are theories none of them have been proven
