TLDR
The temporal induction curves for color and brightness were very similar, however, brightness induction was found to increase approximately linearly with increasing surround modulation up to very high levels, whereas the amount of color induction was much less dependent on the modulation depth of the surround.About:

Finding out about filling-in: a guide to perceptual completion for visual science and the philosophy of perception.
TL;DR: A taxonomy of perceptual completion phenomena is presented to organize and clarify theoretical and empirical discussion, and certain forms of visual completion seem to involve spatially propagating neural activity (neural filling-in).
Journal ArticleDOI
Contextual influences on visual processing.
TL;DR: This work reviews a number of recent studies that have used a context-based approach to explore the neuronal bases of visual scene perception and shows that neuronal sensitivity must be assessed in varied contexts that differentially influence perceptual interpretation.

The Representation of Brightness in Primary Visual Cortex
TL;DR: A significant percentage of neurons in primary visual cortex were shown to respond in a manner correlated with perceived brightness, rather than responding strictly to the light level in the receptive fields of the cells, suggesting that even at the first stage of visual cortical processing, spatial integration of information yields perceptual qualities that are only indirectly related to the pattern of illumination of the retina.

Seeing slow and seeing fast: two limits on perception.
TL;DR: Video cameras have a single temporal limit set by the frame rate, but the human visual system has multiple temporal limits set by its various constituent mechanisms, which seem to form two groups that collaborate to create the unified visual experience.

Neural representation of the luminance and brightness of a uniform surface in the macaque primary visual cortex.
TL;DR: It is indicated that global luminance information significantly modulates the activity of surface-responsive V1 neurons and that not only physical luminance, but also perceived brightness, of a homogeneous surface is represented in V1.

An opponent-process theory of color vision.
Leo M. Hurvich,Dorothea Jameson +1 more
TL;DR: Throughout some hundred years since the original formulation of the idea, a continued series of attempts has been made to find the proper transformation of the three measured colormixture curves that will bridge the gap and yield the unique spectral distribution curves of the desired physiological correlates of theThree postulated "fundamental" color sensations.

Contrast constancy: deblurring in human vision by spatial frequency channels.
Mark A. Georgeson,G.D. Sullivan +1 more
TL;DR: It is argued that spatial frequency channels in the visual cortex are organized to compensate for earlier attenuation, and achieves a dramatic 'deblurring' of the image, and optimizes the clarity of vision.

A spatial frequency dependent grating-induction effect
TL;DR: Observations indicate that the neural locus of this induction effect is cortical, lying at or beyond the level of spatial frequency selective channels, and square wave inducing gratings produce weaker induction effects than sinewave inducing gratINGS of the same spatial frequency and contrast.

Spatiotemporal chromaticity discrimination.
TL;DR: The experiments indicate that no resonance phenomena occur in the spatiotemporal color-discrimination system of the eye, and show that the threshold chromatic contrast is proportional to the square root of the illuminance.
