How is the analytical and synthetic function of the human brain carried out?

Analytical and synthetic functions do not work alone – they are linked to one another. Everything that we receive from the outside: sounds, smells, pictures, touches – affects our receptors, each impact on its own type of receptors. Further, along the nerve fiber in the form of impulses, these data enter the brain. There information is analyzed, all data is grouped, synthesized and distributed across the areas of the brain. Our brain evaluates information in terms of its significance, importance for us, divides it into important and not very important, secondary.
