Physiological Postnatal Neurogenesis, Development, and Maturation in the Regenerable Retina
ABSTRACT The retina enlarges postnatally by ∼440% in axolotls and ∼150% in humans, predicting a reduction in neuron densities by 81.5% and 60%, respectively, if neurogenesis is absent. The concurrent retinal remodeling is poorly characterized. We studied retinas of 2–15 cm axolotls. Results showed that hatchling (∼2 cm...
