Color in the Cortex (Color Vision in Form and Shape Perception (findings…

- - - - detection thresholds reveal only the most sensitive phychophysical mechanisms
        
        V1 color-only cells are most sensitive to cone contrast
        
        half of V1 neurons respond to chromatic stimuli at detection threshold but respond to achromatic modulation only at high contrast
      - color-luminance responses may be nonlinearly mediated at cortical level
        
        the nonlinear combination might only be reveal under specific conditions
        
        suprathreshold achromatic contrast facilitate chromatic detection
        
        nonlinear combinations of chromatic and achromatic contrast in V1 enhance color processing by achromatic contrast
      - color and luminance contrasts interact at suprathreshold levels
        
        interaction a suprathreshold is compatible with independent mechanisms at near threshold levels
