TLDR
Receptive field centre sizes of brisk‐sustained (X) and brisk‐transient (Y) ganglion cells of the cat retina were assessed by three different methods: small spot mapping, area threshold method and spatial resolution.Abstract:
1. Receptive field centre sizes of brisk-sustained (X) and brisk-transient (Y) ganglion cells of the cat retina were assessed by three different methods: small spot mapping, area threshold method and spatial resolution. 2. Centre sizes of brisk-sustained (X) cells increased from 20' in the central area to about 70' at an eccentricity of 4.5 mm, centre sizes of brisk-transient (Y) cells from 50' in the central area to about 140' at 5 mm eccentricity. 3. The scatter of centre sizes at one retinal location was measured by recording as many ganglion cells as possible in one cat in a small field of retina. The centre sizes of the individual classes were homogeneous and exhibited only a small amount of scatter. 4. The coverage of the retina by the different ganglion cell classes was assessed from their density and their receptive field centre area. At every retinal location the receptive field centres of seven to twenty brisk-sustained (X) cells and of three to six brisk-transient (Y) cells were found to overlap. Sluggish concentric and non-concentric cells taken together have a coverage factor of about 60.read more

Theory of Edge Detection
David Marr,Ellen C. Hildreth +1 more
TL;DR: The theory of edge detection explains several basic psychophysical findings, and the operation of forming oriented zero-crossing segments from the output of centre-surround ∇2G filters acting on the image forms the basis for a physiological model of simple cells.

An emergent model of orientation selectivity in cat visual cortical simple cells
TL;DR: A 1:4 scale model of a 1700 microns by 200 microms region of layer IV of cat primary visual cortex is presented to demonstrate that local intracortical excitation may provide the dominant source of orientation-selective input and provide a unified account of intracellular and extracellular inhibitory blockade experiments that had previously appeared to conflict over the role of inhibition.

Peripheral vision and pattern recognition: a review.
TL;DR: It is reported that peripheral vision is limited with regard to pattern categorization by a distinctly lower representational complexity and processing speed than those imposed on low-level functions and by way of crowding.

Retinal ganglion cells that project to the dorsal lateral geniculate nucleus in the macaque monkey
V.H. Perry,R. Oehler,Alan Cowey +2 more
TL;DR: Comparing the results with those of comparable investigations on cats and rabbits shows a much clearer segregation of the terminal targets of different classes of ganglion cell in monkeys, the greatest difference being the absence in the monkey of a projection to the geniculate from gamma- and epsilon-like cells.

Directional Selectivity and its Use in Early Visual Processing
David Marr,Shimon Ullman +1 more
TL;DR: The second part of the paper suggests a specific model of the information processing by the X and Y cells of the retina and lateral geniculate nucleus, and certain classes of cortical simple cells.

Discharge patterns and functional organization of mammalian retina
TL;DR: 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.
Journal ArticleDOI
The contrast sensitivity of retinal ganglion cells of the cat.
TL;DR: Spatial summation within cat retinal receptive fields was studied by recording from optic‐tract fibres the responses of ganglion cells to grating patterns whose luminance perpendicular to the bars varied sinusoidally about the mean level.

Sustained and transient neurones in the cat's retina and lateral geniculate nucleus.
TL;DR: Cat retinal ganglion cells may be subdivided into sustained and transient response‐types by the application of a battery of simple tests based on responses to standing contrast, fine grating patterns, size and speed of contrasting targets, and on the presence or absence of the periphery effect.

Organization of the primate retina: electron microscopy.
TL;DR: The retinae of monkey and man have been studied by electron microscopy to identify cell types, their processes and synaptic contacts, and a model of the retina, based on the described anatomy, is presented and correlated with ganglion cell physiology.

The morphological types of ganglion cells of the domestic cat's retina.
TL;DR: Three distinct morphological types of cat retinal ganglion cells have been identified and categorized as α, β and γ and these cells have dendritic field diameters from 180 to 1000 μm.
