In this case, the changing illuminations first interact with the objects in the scene, generating time-varying sequences of color signals.
Effects of background illuminations on the receptive field size of horizontal cells in the tur tle retina are mediated by dopamine.
Prediction of color appearance with different adaptation illuminations.
Indeed, it is plausible that this aspect of color vision is more important than seeing objects that are already visible as having the same color across differing illuminations.
Moreover, the interest of the book lies not just in the elegant explanatory model that he has developed and the illuminations that flow from his use of political science concepts.
A challenge has been to devise a set of stimulus and viewing conditions that afford evaluation of the receptor types that mediate the color percepts under dim illuminations.
Thus, from the point of view of chromatic diversity, this would not be the ideal illumination for the paintings tested here.
Photoresponses were elicited by long-wavelength and shor t-wavelength light stimuli in the dark-adapted state and under conditions of chromatic background illumination.
