[Consciousness, its criteria and the possible mechanisms].

Consciousness is characterized by the objective and subjective criteria. Accordingly, this is the ability to operation with knowledge, its transmission to other people in abstract form and the feeling of "ego" as a subject of these actions. Objective and subjective signs of the consciousness are provided with the mechanism based on the synthesis of information coming from organs of sensation extracted from memory and coming from the centers of emotions and motivations. As a result of this synthesis the sensation of "ego", appears, and information estranged from it and offered for others is determined. An important role in the informational synthesis is played by the dynamic cortical structures--foci of interaction. In the process of perception they are localized mostly in projective zones of analyzers, at thinking--in associative zones of the cortex. Realization is closely connected with communication and formation of foci of interaction in the verbal zones of the left hemisphere.
