One of the reasons why we have the greatest visual acuity at the fovea centralis of the macula lutea is because, while it is densely saturated with photoreceptors, the circuit arrangement is such that only a few of them are associated with each bipolar cell creating (less or more) convergence in this region, thus allowing for (less or more) discrimination between incoming signals.
