We investigated receptive field properties of cat retinal ganglion cells with visual stimuli
which were sinusoidal spatial gratings amplitude modulated in time by a sum of sinusoids …

1. The mechanism which makes Y cells different from X cells was investigated. 2. Spatial
frequency contrast sensitivity functions for the fundamental and second harmonic responses …

Spatiotemporal frequency responses were measured at different levels of light adaptation for
cat X and Y retinal ganglion cells. Stationary sinusoidal luminance gratings whose contrast …

Receptive fields of cat retinal ganglion cells were stimulated by a drifting, sinusoidal
luminance pattern of fixed contrast. The amplitudes and phases of the harmonic components …

1. The discharges of single X and Y ganglion cells (distinguished by a test of linearity of
spatial summation) were recorded in the optic tract of anaesthetized, paralysed cats. 2 …

1. A model is proposed for the effect of contrast on the first‐order frequency responses of cat
retinal ganglion cells. The model consists of several cascaded low pass filters ('leaky …

The spatio‐temporal characteristics of cat retinal ganglion cells showing linear summation
have been studied by measuring both magnitude and phase of the responses of these cells …

Extracellular microelectrode recordings were made from ganglion cells of the intact, in situ
eyes of adult common domestic cats. Three different photopic systems, with peak spectral …

Studies on the receptive field properties of cat retinal ganglion cells over the past half-
century are reviewed within the context of the role played by the receptive field in visual …

1. Variation in stimulus contrast produces a marked effect on the dynamics of the cat retina.
This contrast effect was investigated by measurement of the responses of X and Y ganglion …
