The book examines behavioral problems that arose as a result of unusual evolution, artificial selection and design features of the human brain. The paradoxical principles of the morphofunctional organization of the brain, the origin of thinking, the duality of consciousness, the structural basis of gender and individual differences are discussed. Special chapters analyze the mechanisms of formation of social instincts and cerebral patterns of community development. The publication is intended for a wide range of readers, who sometimes attended high school and retained traces of consciousness.
