Abstract

Event-related potentials (ERP) traditionally on 42 healthy subjects (men) aged 20–28 years were recorded. The visual images were a line of visual images with an incomplete set of signs, as well as images-illusions, which, with different perceptions, represent different images. The article discusses the results of original research in the context of the discussion of modern studies of the well-known psychological phenomenon of P300 evoked potentials. Thus, the main trends in the change in ERP depending on the variants of recognition of visual illusions and oddball images are as follows. Complete recognition of illusions, which corresponded to insight in the model of our experiment, was accompanied by an increase in the amplitude of the P300 wave in the temporal-parietal regions on the right. With correct identification of one of the dual images, the activation of the N450 component was recorded in the frontal regions on both sides. Negative recognition was characterized by generalized symmetric activation of all ERP components, more pronounced in the posterior half of the brain.
