Corollary discharge: Its possible implications in visual and oculomotor interactions

Abstract

Abstract--Data concerning the possible role of a corollary discharge mechanism in the regulation of visual-oculomotor interactions are reviewed. Several modes of action for such a mechanism on the processing of visual information are discussed. Mere suppression of visual input during saccades is considered mostly as a peripheral mechanism. It is proposed that corollary discharge could either produce an active cancellation of the effects of eye movements on vision, or contribute to the evaluation that a given visual change is provoked by a saccade. Cancellation could occur at subcortical levels of visual processing although evaluation could occur at the cortical level.

What does linear vection tell us about the optokinetic pathway?

“…The idea of a vestibularly induced kind of efference copy was first proposed by Sperry (1950), who called it a "corollary discharge." This term often features in the inferential literature (see, e.g., Jeannerod et al 1979). To a certain extent the present model agrees with this idea.…”

“…Answers to this question can be classified in two main theoretical approaches. According to the traditional view, here called inferential theory, we perceive the motion or stationarity of an object, or of the visual world itself, on the basis of the outcome of a comparison between two neural signals (see e.g., Helmholtz 1910;Jeannerod et al 1979;MacKay 1972; Mittelstaedt 1990;Sperry 1950;Von Hoist & Mittelstaedt 1950). One signal, here to be called the retinal signal, consists of retinal afferents encoding the characteristics of the movement of the objects' image across the retina.…”

Learning and Decay of Prediction in Object Manipulation

“…Such models are known as forward models as they capture the forward or causal relationship between actions, as signaled by efference copy (Jeannerod et al 1979;Sperry 1950;von Helmholtz 1867;von Holst 1954) and outcome. Forward models have been proposed to play a fundamental role in motor planning, execution, and learning (Jordan 1995;Jordan and Rumelhart 1992;Kawato et al 1987;Miall and Wolpert 1996;Wolpert 1997;Wolpert et al 1995).…”

Induced movement in the visual modality: An overview.

“…These are ( An analysis of visual perception of object motion is complicated by the fact that the eye is in virtually constant movement even during fixation (Ditchburn, 1955;Verheijen, 1961), so that image displacement can arise from both object movement and eye movement with respect to the stationary environment. A solution to this problem may lie in the possibility that perception of the stationary environment is largely achieved through a matching of eye movement and image displacement (Jeannerod, Kennedy, & Magnin, 1979;Teuber, 1960;von Hoist, 1954): If one extrapolates, perception of a moving object could be explained by a failure in matching eye movement and image displacement (e.g., Wertheim, 1981).…”
