How the eye builds circuits to detect motion

How the eye builds circuits to detect motion: "The brain works asymmetrically. Generally known is the fact that the left half of the brain performs different computations than the right half. But it does not end there, asymmetry is also found on a cellular level. Nerve cells in our eyes that react to movements from right to left are not active, when something moves from left to right and vice versa. Movement is only recorded in one direction. What is more, similar asymmetries are the basis for many brain computations. However, how and when this asymmetry develops was not known."
