Central Brain Circuitry for Color-Vision-Modulated Behaviors.

摘要: Color is famous for not existing in the external world: our brains create perception of color from spatial and temporal patterns wavelength intensity light. For an intangible quality, we have detailed knowledge its origins consequences. Much known about organization evolution first phases processing, filtering light eye processing retina, final phases, roles behavior natural selection. To understand how central brain has evolved, need well-defined pathways or circuitry where can gauge contributes to computations involved specific behaviors. Examples such that are dedicated cues rare, despite separation luminance early visual system many species, traditional definition as being independent luminance. This minireview presents examples which vision behaviors dominated by other modalities, part canon circuitry. The process a range chromatic properties objects their illumination, taken variety species. By considering complements rather than it, gain additional way account diversity coding brain, consequences ultimately vision.
