Summary
Amongst mammalian species, the diameter of the eye varies by more than an order of magnitude. Objects in visual space traverse the surface of the retina of a large diameter eye at a higher velocity than that of a small diameter eye, raising the question of how different species encode the velocity of moving objects. Using comparative connectomics and computational modelling, we identified a difference in the placement of synapses among neurons in the mouse versus rabbit retina. Our results suggest an adaptation in neural wiring that compensates for eye diameter differences across species.
