The phenomenon of cephalization. Part three

He is almost unbelievable, assuming his accidental education. It determines the best paths to the richest storehouses of energy. Like a thin ray of the star Arcturus, the information generated by the brain finds a single point, the faint touch of which serves as a signal for subsequent avalanche processes. Of course, the potential energy of an avalanche and the tense, not too stable state of its constituent elements are very significant. At the Chicago Expo, the electronic avalanche was artfully prepared ahead of time. Even without this, there are more or less abundant storehouses of energy in nature. It is very useful to choose the most appropriate search strategy. Let's not try to numerically express the amount of information in the nervous systems of different animals now. Let's limit ourselves to definitions like "less is more". That's enough. In primitive multicellular organisms, the nervous system is organized almost chaotically and consists of a small number of cells. Therefore, it can contain and extract relatively little information from any situations. Experiments have shown that these animals have almost no memory and are able to produce only the simplest conditioned reflexes in response to stimuli. For example, they go to their goal time after time in the only way achievable for them, by alternating trials, resembling most current computers. Primitive vertebrates are essentially the same. After 30-40 lessons, lancelets "understand" that an electric shock should fall on them after a ray of light, and they try to avoid the light. However, the next day, half of the lancelets forget the past and learn to escape anew. The same thing happened on the third day. However, it is not only the "poor academic performance" of all lancelets in general that is important here, but their division into the memorable and the forgetful, into relatively good students and bad ones.


It is important to show individuality, different memorizing abilities, and the preservation of "conditioned reflexes" (I put quotation marks because a number of scientists do not consider such actions to be reflex). Primitive multicellular animals (including the first chordates) have similarities with unicellular ones in terms of reactions to irritation. Even the infusoria, which has no nervous system, learns something. A simple nervous system does not provide noticeable advantages to its owners. It helps to coordinate the actions of different parts of the body, and even that is not good enough. It develops at first as something not too necessary, perhaps as an "excess". 1xbet 프로모션코드
