Luminance and opponent color contributions to visual detection and to temporal and spatial integration: comment. 1978

C R Ingling, and P E King-Smith, and D Carden

King-Smith and Carden have postulated a "luminance system" or achromatic channel in the visual system which has a temporal response better than the other channels, and which also responds to high spatial frequencies better than the other channels. All evidence, both psychophysical and electrophysiological, indicates that these properties are contradictory.

UI MeSH Term Description Entries
D014785 Vision, Ocular The process in which light signals are transformed by the PHOTORECEPTOR CELLS into electrical signals which can then be transmitted to the brain. Vision,Light Signal Transduction, Visual,Ocular Vision,Visual Light Signal Transduction,Visual Phototransduction,Visual Transduction,Phototransduction, Visual,Transduction, Visual
D014792 Visual Acuity Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast. Acuities, Visual,Acuity, Visual,Visual Acuities
