Central and Peripheral Features of Crayfish Oculomotor Organization
Animals which see utilize a number of reflex movements tending to stabilize on the retina those features of the visual environment which have immediate selective value. The movements may themselves be evoked by visual events, as in optomotor or optokinetic reactions, and compensatory behavior can involve the head or even the entire body. In vertebrates, some mollusks, and a number of crustaceans, however, the retinal surfaces are mounted on paired platforms which are capable of movement relative to the head proper. In these animals, many visual stabilization reflexes are the sole domain of an independent oculomotor system.
