To investigate the somatotopic conservation in amniote evolution, we compared trigeminal nerve somatotopy in turtles, birds, and mice. Our results suggest that while the basic developmental and molecular mechanisms underlying the wiring of distinct facial regions into the brain are conserved, the fine spatial organization of trigeminal ganglion and target hindbrain trigeminal nuclei has undergone several changes during the course of amniote evolution.
