Walsh & Hoyt: Extraocular Muscle Afferents

The trigeminal pathways of the extraocular muscle afferents are becoming more clearly delineated and it is evident that proprioceptive information is important at least in eye movement control and perhaps also in other visual functions. The central nervous system has three possible ways of checking eye movement accuracy: visual feedback, corollary discharge (an internal efference copy of the motor command), and eye muscle proprioception.
