TLDR
Among the ganglion cells in the rabbit's retina there is a class that responds to movement of a stimulus in one direction, and does not respond to movement in the opposite direction, but the selected direction differs in different cells.Abstract:
Among the ganglion cells in the rabbit's retina there is a class that responds to movement of a stimulus in one direction, and does not respond to movement in the opposite direction. The same directional selectivity holds over the whole receptive field of one such cell, but the selected direction differs in different cells. The discharge is almost uninfluenced by the intensity of the stimulus spot, and the response occurs for the same direction of movement when a black spot is substituted for a light spot.read more

The Measurement of Visual Motion
Ellen C. Hildreth,Shimon Ullman +1 more
TL;DR: The analysis of visual motion plays a central role in biological systems as discussed by the authors, and sophisticated mechanisms for extracting and utilizing motion exist even in simple animals, such as frogs and houseflies, that respond selectively to small, dark objects moving in its visual field.

TL;DR: It is shown that expression of archaebacterial halorhodopsin in light-insensitive cones can substitute for the native phototransduction cascade and restore light sensitivity in mouse models of retinitis pigmentosa.

Organization of the Primate Retina: Light Microscopy
TL;DR: The structure of the human, but mainly of the rhesus monkey, retina as examined by Golgi-staining techniques is described and interpreted on evidence from both light and electron microscopy.

Evidence for a physiological explanation of the waterfall phenomenon and figural after-effects.
Horace Barlow,Richard M. Hill +1 more
TL;DR: The rabbit's retina ganglion cells have recently been found which signal the direction of motion of objects moving in the visual field, and the behaviour is what one might expect in units of which the function is to abstract direction ofmotion from the pattern of light falling on the retina.

Receptive fields, binocular interaction and functional architecture in the cat's visual cortex
David H. Hubel,Torsten N. Wiesel +1 more
TL;DR: 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.

Receptive fields of single neurones in the cat's striate cortex
David H. Hubel,Torsten N. Wiesel +1 more
TL;DR: 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.

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.

What the Frog's Eye Tells the Frog's Brain
TL;DR: The results show that for the most part within that area of the optic nerve of a frog, it is not the light intensity itself but rather the pattern of local variation of intensity that is the exciting factor.
