ense of smell, but in which it is impossible to develop reflexes to new situations, for example, in insects. The analogues of the "C" informant are all "remote" receptors: eyesight (or its photosensitive analogues in inferior animals), hearing and sense of smell. The analogues of analyzer-classifier are, for example, visual, acoustical, gustatory and olfactory analyzers located in the subcortex. Visual, acoustical, gustatory and olfactory analyzers located in the cerebral cortex are anyway referred to analyzers-correlators. p> Self-training control block. No brain is able to hold enormous "knowledge bases" on all possible conditions of the entire world around. Therefore, one of the reasons why each species of animals occupies corresponding biosphere niche is the necessity to limit the volume of "knowledge base". Antelope knows what the seal does not, and vice versa. In each separate ecological niche the quantity of possible situations is much less, than in all ecological niches all together. Therefore, relatively small volume of necessary knowledge is required in separate ecological niches. However, if one tries to somehow input/in the brain/all the information currently available on all the situations which have already been occurring in the world, it would not help either, because the world alters continually and many situations have never ever arose. The "knowledge base" basically may not have information on what has not yet happened in the world. Naturally, the "base of decisions" cannot contain all the possible options of decisions either. "Genetic knowledge "contains only what the ancestors of animals have experienced. They materially cannot have knowledge of what is going to happen. When new situation arises, the system cannot identify, classify it and make decision on it. Even if this situation will occur repeatedly, if the system is unable of self-training it will every time fail to correctly identify a situation because such situations are not contained in its "knowledge base". The ant runs along the fence, going up and down, and cannot guess that it is possible to easily bypass the fence. Millions years ago, when its genetically input "knowledge base "was formed the fences were non-existent. If one tries to sink a thread on the web the spider will leave this web and will weave a new one because it is not familiar with such situation and it does not know and cannot learn that it is possible to make a hole in a web so that the thread does not interfere. All this is due to the fact that insects as a class of animals are not capable of learning anything. They may be perfect builders amazing us with their sophisticated and fine webs, nests and other creations of their work. But they can only build based on their innate knowledge. They do have "knowledge base" (Instincts), but they do not have cerebral structures (elements of control block) capable of supplementing their own "knowledge base" with new existential situati...
