[Attention and eye movements in human: psychophysiological concepts, neurophysiological models and EEG correlates]

A review. Recently published articles concerning the problem of attention are discussed, the most popular psychophysiological concepts and neurophysiological models of attention are described, and correlation of spatial attention and saccadic eyes movements is shown. The evidence for reflection of attention mechanisms and saccade preparation in intensity and topography of the visual evoked potentials and event-related potentials is given. On the basis of the results obtained by the authors and literature data, the contribution of attention to preparation of a saccade and its programming is shown. Different kinds of attention are reflected in a complex of EEG potentials of various duration and polarity. The analysis of parameters and topography of these potentials can serve a tool for investigation of the attention mechanisms.
