title: [Electric reactive potentials to events of a positive and negative emotional nature].
abstract: The event-related potentials (ERP) in the frontal and posterior associative cortex in the right and left hemispheres were studied in two different outcomes of tennis television game. These outcomes were "win" and "loss" of the ball, the first serving as a model of positive, the second--of negative emotional reactions. The averaging procedure was synchronized with the moment of ball crossing the racket line. The ERP consisted of four waves: P300, N600, P800, N1000. The most characteristic interhemispheric difference for the win was an increase of N600 wave in the left posterior associative cortex and for the loss--a decrease of P800 wave in the right frontal area. Thus the positive and negative emotional reactions have specific spatiotemporal organization and are based on complicated interaction of cortical areas.
