nervous system
• sympathetic neurons of the superior cervical ganglion (SCG) have improper pruning of axons from neurons that reach into both eye compartments
• by 50 days of age, wild-type mice prune axons from SCG so that only 36% of SCG neurons reach into both eyes
• mutant mice have less axon pruning, which leads to 51% of SCG neurons projecting into both eyes at 50 days of age
