THEIMPORTANCEOFNORMALSENSORYSTIMULATION inthedevelopment and maintenance of the nervous system is now generally recognized. In the visual system this problem has usually been approached by examining the effects of sensory deprivation on structure and behavior (see reviews by Hebb (12) and Riesen (28)). An obvious way of extending this work would be to examine electrophysiologically the functional effects of visual deprivation, but such experiments require some knowledge of normal function…

Effects of visual deprivation on the development of the monkey's lateral geniculate nucleus.
TLDR
Although the post‐natal maturation of visual acuity in normal monkeys seems to be mainly limited by peripheral factors, deprivation does not seem to interfere substantially with physiological development of the retina or the geniculate nucleus in monkeys monocularly deprived from birth.
Monocular deprivation and the signal transmission by X- and Y-neurons of the cat lateral geniculate nucleus
TLDR
The pattern deprivation effects found morphologically and physiologically in the visual cortex are, therefore, not induced by a diminished average activity of the input neurons from the deprived eye.
Effects of monocular deprivation on the structure-function relationship of individual neurons in the cat's lateral geniculate nucleus
TLDR
Soma size measurements indicate that the abnormally small somata found in deprived geniculate laminae result from a selective effect on Y-cells, and this analysis is extended in cats reared with monocular eyelid suture to 24geniculate neurons innervated by the sutured eye in lamina A or A1.

TLDR
The anatomic and physiological effects of depriving kittens of vision in one eye for various lengths of time and at various ages 7,s are summarized.
Effects of early monocular deprivation on development of cortico-geniculate projections in the cat
TLDR
It is suggested that normal maturation of cortico-geniculate cells, particularly fast and intermediate ones, is retarded or arrested by monocular visual deprivation.
Effect of sensory disuse on geniculate afferents to cat visual cortex.
TLDR
The morphology of geniculocortical arbors in kittens deprived of patterned vision by binocular lid suture for 1 week or 2 weeks and with arbors obtained in age-matched normal controls support the notion that competitive mechanisms rather than sensory disuse are responsible for gross morphological remodeling of geningal arbors.
Permanent perceptual and neurophysiological effects of visual deprivation in the cat
TLDR
It is concluded that when forced to use an eye which influences only a small number of neurons, all of which have abnormal receptive fields, animals can learn a wide variety of form problems, but only by using local flux cues.
Loss of a specific cell type from dorsal lateral geniculate nucleus in visually deprived cats.
TLDR
Evidence is presented that one effect of rearing cats with visual deprivation is the selective elimination from the LGNd of Y-cells, and the remaining neurons appear to be functionally normal.

THIS book is not a general treatise on vision, but in deals with some additions to visual physiology in the last fifteen years that have been derived from the study of action potentials of the retina

TLDR
Methods for stereotaxic depth recordings in the unanaesthetized unrestrained animal were developed in order to make cortical and depth studies under similar conditions and make it possible to record from single units from virtually any part of the brain of the freely moving animal.
Receptive fields, binocular interaction and functional architecture in the cat's visual cortex
TLDR
This method is used to examine receptive fields of a more complex type and to make additional observations on binocular interaction and this approach is necessary in order to understand the behaviour of individual cells, but it fails to deal with the problem of the relationship of one cell to its neighbours.
Discharge patterns and functional organization of mammalian retina.
TLDR
The Limulus preparation shows many features which are similar to other simple sense organs, for instance, stretch receptors, however, instead of photochemical events, stretch-deformation acts as the adequate stimulus on sensory terminals and is translated into a characteristic discharge pattern.
Receptive fields of single neurones in the cat's striate cortex
TLDR
The present investigation, made in acute preparations, includes a study of receptive fields of cells in the cat's striate cortex, which resembled retinal ganglion-cell receptive fields, but the shape and arrangement of excitatory and inhibitory areas differed strikingly from the concentric pattern found in retinalganglion cells.

TLDR
A method for unit recording from the cortex of unanaesthetized, unrestrained cats is described, some observations from the striate cortex are presented, and the objectives have been to observe maintained unit activity under various conditions such as sleep and wakefulness.
RECEPTIVE FIELDS OF CELLS IN STRIATE CORTEX OF VERY YOUNG, VISUALLY INEXPERIENCED KITTENS.
TLDR
The purpose was to learn the age at which cortical cells have normal, adult-type receptive fields, and to find out whether such fields exist even in animals that have had no patterned visual stimulation.
