Spatial properties of red-green and yellow-blue perceptual opponent-color response. 1984

S Takahashi, and Y Ejima

Opponent color responses for an equal illuminance spectrum were measured for field size from 10' to 2 degrees, by means of a hue cancellation procedure. Results showed that when the field diameter was increased, the red and yellow response relatively increased and the green and blue response relatively decreased. There existed a different spatial property between the red-green and yellow-blue opponent-color response function. The results were compared with the optical density hypothesis of the cone visual pigments and with the neurophysiologically obtained receptive field properties of opponent-color cells.

UI	MeSH Term	Description	Entries
D010786	Photoreceptor Cells	Specialized cells that detect and transduce light. They are classified into two types based on their light reception structure, the ciliary photoreceptors and the rhabdomeric photoreceptors with MICROVILLI. Ciliary photoreceptor cells use OPSINS that activate a PHOSPHODIESTERASE phosphodiesterase cascade. Rhabdomeric photoreceptor cells use opsins that activate a PHOSPHOLIPASE C cascade.

D003118	Color Perception	Mental processing of chromatic signals (COLOR VISION) from the eye by the VISUAL CORTEX where they are converted into symbolic representations. Color perception involves numerous neurons, and is influenced not only by the distribution of wavelengths from the viewed object, but also by its background color and brightness contrast at its boundary.
