opponency造句

• Hering instead believed that the visual system worked based on a system of color opponency.
• But his more recent view locates color in spectral opponency cells deeper in the color information stream.
• In 1957, Leo Hurvich and Dorothea Jameson provided quantitative data for Hering's color opponency theory.
• The color hexagon : a chromaticity diagram based on photoreceptor excitations as a generalized representation of colour opponency.
• The underlying physiological mechanisms involved in color opponency include the mixing pigments, as a system of subtractive color.
• This is often thought to correspond to blue yellow opponency, but actually runs along a color axis from lime green to violet.
• Hsieh and Tse in 2006 disputed the existence of colors forbidden by opponency theory and claimed they are, in reality, intermediate colors.
• Overall, the advantage gained from increased sensitivity with wavelength opponency would open up opportunities for future exploitation by mutations and even further improvement.
• A theory of spectral opponency, in which the addition of other spectral colors renders blue light less effective for circadian phototransduction, was supported by research reported in 2005.
• Some midget retinal ganglion cells oppose L and M cone activity, which corresponds loosely to red green opponency, but actually runs along an axis from blue-green to magenta.
• This led them to propose a " soft-wired model of cortical color opponency ", in which populations of neurons compete to fire and in which the " losing " neurons go completely silent.
• Though these two theories were initially thought to be at odds, it later came to be understood that the mechanisms responsible for color opponency receive signals from the three types of cones and process them at a more complex level.
• Secondly, new random connections would create wavelength opponency and the new wavelength opponent neurons would be much more sensitive than the non-wavelength opponent neurons . This is the result of some wavelength distributions favouring excitation instead of inhibition.
