1. The dynamics of the centre mechanism of individual cat X retinal ganglion cells is
investigated. The visual stimuli consist of temporal contrast modulation of stationary patterns …

1. The dynamics of the subunit mechanism of individual cat Y retinal ganglion cells are
investigated. In order to isolate the response of the non‐linear subunit mechanism, the …

1. The morphology of 21 physiologically characterized X-cells in the cat retina was studied
using intracellular recording and injection with horseradish peroxidase. The data from these …

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 …

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 …

1. Y‐type ganglion cells in the cat's retina were stimulated with bars of light and grating
patterns at photopic luminances. Stimuli were stationary, and luminance at each point was …

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 …

1. The shared inputs to cat retinal ganglion cells have been investigated by studying
correlations in the maintained firing of neighboring ganglion cells. The firing of one cell was …

326 DN MASTRONARDE sustained response than Y-cells to a central stimulus because
they receive stronger input from cone bipolar cells and that active inputs serve as a “final …

1. Action potentials were recorded from single fibres in the optic tract of anaesthetized cats.
2. A sectored disk or 'windmill', concentric with the receptive field, was rotated about its …
