Kathy Mullen "Fall Vision Meeting 2007: Color Processing in the Human LGN and Cortex measured with fMRI"
I will report on our results measuring the fMRI BOLD responses of the different cortical areas and the LGN to chromatic and achromatic stimuli. We used an fMRI (4T) experimental protocol that controls for attention and allows us to compare responses to L/M opponent (RG), S-cone (BY) and achromati...

John S. Werner "OSA Fall Vision Meeting 2013: Color Transformations Across the Life Span: Circuits to Compensation"
The lecture addresses two fundamental questions about color vision and aging. First, what are the mechanisms responsible for changes in chromatic sensitivity from infancy to old age? Psychophysical methods can be used to identify the optical and retinal origins of these changes, but also may serv...
