Expansion of the visual projection to the tectum of axolotls during metamorphosis

During artificially induced metamorphosis in axolotls, the indirect visual projection from the ipsilateral eye develops followed by the expansion of the contralateral direct projection to occupy most of the tectal surface. During expansion the ipsilateral input is temporarily lost indicating the fun...

Summary:During artificially induced metamorphosis in axolotls, the indirect visual projection from the ipsilateral eye develops followed by the expansion of the contralateral direct projection to occupy most of the tectal surface. During expansion the ipsilateral input is temporarily lost indicating the functional interdependence of the two projections. Final stabilization of the projections and congruence of the ipsilateral and contralateral inputs is achieved a month after arrival on land.
