By studying how retinal neurons calculate the direction of movement, researchers have hoped to learn general lessons about how brain neurons compute. But the studies were handicapped because no one knew which retinal neurons do the math. Now, on page 2347, a team reports evidence that the directional computations take place in retinal neurons called ganglion cells.
