visual receptive fields question

Contrast sensative cells get a lot of attention.  On-center, off-center,
line, edge, etc.  Is there any evidence that there are cells anywhere in
the visual system that respond positively to a lack of contrast, to
smooth excitation across the receptive field?

I'm working in robotics and computer vision and have some ideas but I
prefer the artificial life approach and only want to expand on my ideas
if they are biologically accurate.

Thanks.
