Retinae placed in the cortex of neonatal rodents show substantial outgrowth, both along the subpial margin and within the cortical white matter, which is not sustained beyond 6 days post-transplantation. These results, in combination with previous studies, suggest that optic axon outgrowth is sustained for a finite period, after which it requires target-derived influences for its long-term maintenance.
