Spatial properties of the cat X-cell receptive field as a function of mean light level.
TL;DR: The objective with this study was to provide a near complete characterization of how mean light level changes the spatial receptive-field properties of X-cells, and among the major findings are that Weber's Law is followed throughout the photopic but not the scotopic range, that center radius expands underScotopic conditions, and that the surround is present even at the lowest scotopy levels the authors studied.
Journal ArticleDOI
Characteristics of the Sony Multiscan 17se Trinitron color graphic display
TL;DR: Technical measurements of the Sony Multiscan 17se were made and are reported in the belief that they would be useful to visual scientists who consider employing this device as a display unit.
Journal ArticleDOI
The cat's pupillary light response under urethane anesthesia
TL;DR: It was found that the pupillary response of the urethane-anesthetized cat's eyes to light was basically unchanged from that of the alert behaving cat, and this preparation may be a very satisfactory one in which to study the pupilla response pathway in a higher mammal.
Journal ArticleDOI
Spatiotemporal integration of light by the cat X-cell center under photopic and scotopic conditions.
TL;DR: It is found that center radius does not expand with temporal frequency under either low photopic or scotopic conditions, implying that spatial and temporal integration of luminance can be traded for one another by the X-cell center.
Journal ArticleDOI

TL;DR: VSApc is a suite of DOS programs that was developed to measure spatiotemporal frequency responses and to collect maintained discharge from retinal ganglion cells of cats and monkeys.
