TL;DR
While 1.7% of cortical neurons did not respond to any visual stimulus in normal cats, it was 3.9% in cats with convergent squint and 65.2% of the monocular neurons were found to react through the normal eye and the rest through the squinting eye.
Abstract
In five normal cats, 70.7% of the neurons recorded from the visual cortex responded to binocular stimulation; only 27.2% of the neurons in 12 cats raised with convergent squint and 63.6% of neurons in four cats with divergent squint displayed binocularity. In cats with convergent squint, 15% of the neurons showed normal receptive fields through one eye and nonconnected scattered receptive fields through the nondominant eye; however, movement detection, velocity discrimination and unidirectionality were retained. Furthermore, 65.2% of the monocular neurons were found to react through the normal eye and the rest through the squinting eye. While 1.7% of cortical neurons did not respond to any visual stimulus in normal cats, it was 3.9% in cats with convergent squint.

The Journal of PhysiologyThe period of susceptibility to the physiological effects of unilateral eye closure in kittens
3,029 Citations1970David H. Hubel, T. N. Wiesel
Kittens were visually deprived by suturing the lids of the right eye for various periods of time at different ages to study the effect of monocular eye closure on the number of cells that can be influenced by the previously closed eye.
Experimental Brain ResearchResponses to moving slits by single units in cat striate cortex

Optimal stimulus speeds varied widely from unit to unit with a mean at 4°/sec: simple bimodal units and complex units tended to have higher optimal stimulus speeds and responded over a wider range of speeds than did simple unimmodal units.
Brain ResearchEffects of visual deprivation and strabismus on the response of neurons in the visual cortex of the monkey, including studies on the striate and prestriate cortex in the normal animal
253 Citations1974Frank Baker, Peter Grigg +1 more
The neurophysiological results demonstrated changes at the single neuron level which paralleled the degree of the behavioral changes: in animals with very poor acuity in the deprived or deviate eye (the form deprived and one esotropic animal), only a small number of neurons were driven from the operated eye; in one esotrope and the exotropic animal, which had good acuity, many neurons received an input from that eye, but only asmall number of these were binocular.
Vision ResearchSaccadic and disjunctive eye movements in cats
217 Citations1972Michael P. Stryker, Colin Blakemore
Watching eye movements in cats with their heads immobilized reveals disjunctive movements are difficult to elicit repeatedly and are generally much slower than the conjugate movements, whose velocity increases with amplitude up to about 300° sec −1.

192 Citations1963G. J. Vakkur, P. O. Bishop +1 more
Certain key parameters of the dioptric system of the eye, such as the total power and the positions of the posterior three cardinal points, have been calculated and the direction of the visual axis in the paralysed cat (position of paralysis) has been determined in relation to the blind spot and the Horsley-Clarke planes of reference.
Brain ResearchDevelopment of interocular alignment in cats
164 Citations1972S. Murray Sherman
Cats require a normal, binocular visual environment during development to achieve the proper interocular alignment, and it is hypothesized that during normal development, the binocular patterned visual input stimulates some part of the cat's visual system to align the eyes properly.
ScienceShift in Binocular Disparity Causes Compensatory Change in the Cortical Structure of Kittens
134 Citations1971Robert Shlaer
Kittens were raised with prisms in front of their eyes which introduced a vertical disparity, and at 4 months of age the disparity necessary to maximally stimulate a sample of binocular cortical cells was determined.
Experimental NeurologyThe selective effect of visual deprivation on receptive field shape determined neurophysiologically
120 Citations1968Leo Ganz, Margaret I. Fitch +1 more
It is concluded that the lack of pattern vision in one eye of a young kitten induces a selective and rather permanent change in the connections of visual radiation fibers onto cortical cells.
Experimental NeurologyThe effect of visual deprivation on perceptual behavior
116 Citations1968Leo Ganz, Margaret I. Fitch
It is concluded that visual cortex neurons with very selective receptive fields are particularly important in mediating visual form discrimination and fine spatial adjustments in visually deprived cats.
British Journal of OphthalmologyIs amblyopia due to inappropriate stimulation of the "sustained" pathway during development?
78 Citations1974Harukuni Ikeda, Michael J. Wright
The authors' neurophysiological investigations on the retina and the visual cortex in the cat which are relevant to the problems of amblyopia are summarized and a hypothesis which is slightly different from that currently accepted is discussed.
Vision ResearchComparative studies on cortical representation of vision
74 Citations1971Clinton N. Woolsey
A new map of visual areas I and II of the cat's cerebral cortex is presented in figurine style and the general plan of representation of the visual field, believed to be homologous with the suprasylvian sulcal area of Clare and Bishop, is illustrated for rabbit, cat and owl monkey.
British Journal of OphthalmologyExperimental analysis of amblyopia and strabismus.
41 Citations1974Colin Blakemore, Richard C. Van Sluyters
Physiological experiments are described and attempts are made to relate them to some of the clinical origins of amblyopia in man, as well as to behavioural evidence that both cats and monkeys normally have stereoscopic vision.

Results indicate that deficits in the neural mechanisms subserving binocular vision can lead to strabismus; and binocularneurones are unnecessary for the initiation of horizontal vergence eye movements.

Anywhere from 200 to 2,000 /tAmps to elicit eye movement, which means considerable current spread, so that the fibers of the underlying white matter, some of which may be quite remote in terms of retinal topography, are stimulated.
Experimental NeurologyBursting patterns of neurons in the cat's visual cortex
8 Citations1974U. Yinon, E. Auerbach
A distinct group of simple and complex cells in cat visual cortex which responded to a moving stimulus in a rhythmic or nonrhythmic series of spike bursts is found.
Vision ResearchReceptive fields and firing patterns of sustained cells in the cat visual cortex
1 Citations1975U. Yinon, E. Auerbach
The differences between the responses to stationary and moving stimuli suggest that cells in the visual cortex can show either sustained or transient behavior, depending on the stimulus type.
