Abstract: Several converging lines of evidence suggest that the integration of binocular visual with binocular proprioceptive information takes place in the lateral geniculate nucleus (LGN) and it is very likely that such integration is necessary for normal binocular vision and depth perception. A naturally occurring visual anomaly, strabismic amblyopia, which results in the lack of normal stereoscopic vision and reduction of visual acuity, may be the outcome of a perturbation of these integrative mechanisms. Monocular paralysis, an experimental manipulation which, in part, serves to mimic some aspects of strabismic amblyopia, has been shown to disrupt binocular-visual/proprioceptive integrative mechanisms and so may serve as a model for some aspects of amblyopia. Monocular paralysis results in a highly reliable decrease in the encounter rate for X cells relative to Y cells in the LGN six days postoperative.
