11. In optic tectum has a layer the marginal layer that is cerebellum-like. 12. Neurons in the superficial layers of the tectum project to corresponding points in Ipc and Imc. 13. These two layers are the tectum and the foot layer, which is just above the intine. 14. First, the retina is connected to the optic tectum by at least three types of midbrain. 15. The optic tectum exists as an ordered localization system, in the form of a topographical map. 16. The LGN also receives some inputs from the optic tectum ( also known as the superior colliculus ). 17. Posterior retinal cells express high Eph level, and their axons will stop more anteriorly in the tectum . 18. Lesioning experiments led to the discovery of pathways extending between the tectum and the thalamic-pretectal region. 19. These small arteries supply portions of the midbrain, especially the superior colliculus, inferior colliculus, and tectum . 20. The tectum and foot layer are separated by a region called the columella, which is composed of strengthening rods.
