1. Properties of the central response mechanism of on‐centre ganglion cells in the cat retina
were studied by recording, from optic tract fibres, responses evoked by stimuli modulated …

1. The mean rate, impulse interval distribution, and pulse number distribution of the
maintained discharge of ganglion cells in the retina of the cat have been studied after …

METHODS A complete description of the apparatus, preparation and calibrations has been
published by Talbot & Kuffler (1952), Kuffler, FitzHugh & Barlow (1957) and Barlow et …

1. The gain of the central response mechanism and the latency of the pure central response
of on‐centre ganglion cells were studied by recording from single optic tract fibres the …

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. The properties of the surround response mechanism of on‐centre cells and its interaction
with the centre mechanism were studied by recording from single optic tract fibres. In many …

The summing properties of ganglion cells in the cat's retina have been examined, using as
stimuli two stationary, flashing spots of light, both positioned within the center regions of the …

METHODS These experiments were designed to determine how the background luminance
affected the response characteristics, including gain and dynamic range, of each type of …

The effects of light adaptation on retinal on-center ganglion cell firing were measured in the
scotopic-mesopic range (10− 5–1 cd/m 2). Using diffuse adapting stimuli, the maintained …

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 …
