[Visual suppression during eye movements (a brief review on the problem of the mechanisms and their role in visual perception). I. A brief review and the mechanisms].
A problem of visual suppression during eye movements is discussed. The short critical review of the main published papers is adduced. A comparative analysis of the literary and author's data has been considered. These data provide evidence for the existence of three but not two (how is maintained) mechanisms of visual suppression: a retinal, efferent copy, and proprioceptive (from extraocular muscles) signals. The proprioceptive mechanism is more powerful than efferent copy. Both retinal and extraretinal mechanisms of visual suppression are discussed in detail. The sources and the passage's pathways of the extraretinal signals are considered thoroughly. It is shown that the retino-geniculate system provide mainly retinal mechanisms vs the tecto-thalamic system provide extraretinal mechanisms.
