Humans and other living things, including plants, communicate information about themselves and the world around them to each other in various ways, including through the brain. If we define the essence of the brain, we must also speak about the concept of consciousness. Consciousness, one of the basic notions of philosophy, sociology and psychology, means the human ability to reproduce reality perfectly in thought. Consciousness is the highest form of mental reflection inherent in a socially developed person and associated with speech, the ideal side of the goal-setting activity. It performs in two forms: individual (personal) and public.
