This review generalizes the data of modern studies of individual peculiarities of the spatial/temporal and amplitude characteristics of evoked EEG potentials (EPs) in humans. A brief description of EPs, characteristics of their components, sources of generation, and functional correlates is presented. Possible effects of the emotional significance of the stimulus and of individual peculiarities of the personality on the amplitude/temporal characteristics of EPs are considered. It is supposed that the aminergic cerebral systems play a crucial role in the formation of peculiarities of emotional responses, expression of the definite EP components, and biologically determined features of the human personality.
