We use a combination of advanced high-density, source-imaged EEG, fMRI and psychophysics to study the dynamics of early visual processing for color and luminance in human V1 and other early visual cortical areas.
The questions we are studying include:
How are color and luminance signals combined in the first few hundred milliseconds after they leave the retina?
How do signls originating in the short-wave-sensitive cones differ from those in other visual pathways?
How does the spatial arrangement of signals influence the way in which they are process and perceived?
How are signals in the early visual system changed by attention?
