Influence of Stimulus Complexity on the Properties of Neural Activity During Perceptual Process

This work is devoted to study of the features of time-frequency EEG structure, related to visual information processing in the brain. As a concrete example, the influence of stimulus complexity on the time-frequency EEG properties is considered. It is shown that an increase of visual stimulus complexity leads to an increase in the response amplitude of the neural network of the brain in the parietal and occipital cortex. It is associated with the excitation of the neural center of visual attention.
