Comparative Neurobiology of the Optokinetic Reflex
A comprehensive overview of the optokinetic reflex (OKR) in vertebrates is given. The main objective is to compare the asymmetry in optokinetic reactions when patterns presented to one eye move horizontally in temporo-nasal or naso-temporal directions. Different hypotheses concerning the evolution of this asymmetry or symmetry in monocular horizontal OKR are discussed.
