TIPS had been quiet lately. A question occurred to me when talking about rod vs cone functioning.
When light levels get low, the cones lose function. Since the fovea is 100% cones, why don't we have a blind spot in the center of our vision in low light, low enough to lose color, but still enough light to move around in a dark room. While the blind spots of right and left eyes can be 'filled in' by information from the other eye, I would think that the foveas would be aimed at exactly the same spot. My first thought would be the memory of looking close to some spot, getting the information with the rods and remembering it when shifting my gaze to that spot. I know memory stuff better than physiology stuff, so I thought that there might be a better or at least a more physio-oriented answer.
