  • Title: Corollary discharge provides accurate eye position information to the oculomotor system.
    Author: Guthrie BL, Porter JD, Sparks DL.
    Journal: Science; 1983 Sep 16; 221(4616):1193-5. PubMed ID: 6612334.
    Abstract:
    The saccadic system accurately compensates for perturbations of eye position produced by microstimulation of the superior colliculus. This requires that information about the stimulation-induced change in eye position be provided by an extraretinal source--either proprioceptive endings in extraocular muscles or a centrally generated corollary discharge. It is shown that compensation remains intact after elimination of extraocular muscle proprioception, demonstrating that corollary discharge provides accurate eye position information.
