[Functional asymmerty of the brain and emotions].
Different kinds of emotional phenomena are related in a different way with the workings of the left and right hemispheres of the brain. Emotional reactions (phasic emotions), which appear on the basis of a cognitive loading (mental representation, recognition, play, prognostication, watching movies, reading of emotionally colored texts or separate words and so on) and which are tested with the help of electrophysiological methods, activate different regions of the left and right hemispheres of the brain depending on the complexity and novelty of emotiogenic situations as well as on the degree of subject's emotional tension. The tonic emotions individual background-mood, on which depends the emotional estimation (negative of positive) of the presented stimuli or events, are determined mostly by a prolonged, relatively stable, tonic activation of each hemisphere connected with subjects' individual characteristics. The predominance of the left hemisphere activity creates positive emotional background, whereas the predominance of the right hemisphere creates negative background.
