Supplementary Figure 5: Effect of starburst-cell ablation on visual reflexes.

(a-b) Pupil reflex test. (a) The pupil of a starburst-ablated mouse is shown in the dark (left) and after a flash of light (right). The extent of the pupil is indicated in white. (b) Quantification of pupil reflex, the relative decrease in pupil diameter after a flash of light, is shown for control and starburst-ablated mice. Black dots: data from individual mice. (c-d) Optokinetic reflex test. (c) Mice were stimulated with gratings moving in a horizontal direction (left). Eye position in response to stimulation before (middle), and seven days after (right) DT injection in the same mouse. Negative deflections indicate eye movements in the anterior (A) direction, while positive deflections indicate eye movements in the posterior (P) direction. (d) Quantification of optokinetic reflex: eye-tracking movements (ETMs) per minute in control and starburst-ablated mice. Black dots: data from individual mice.
