1. In optic tectum has a layer the marginal layer that is cerebellum-like. 2. The superior colliculus / optic tectum forms a major component of the midbrain. 3. In optic tectum has a layer the marginal layer that is cerebellum-like. 4. They presented owls with sound stimuli while recordings were made from the optic tectum . 5. First, the retina is connected to the optic tectum by at least three types of midbrain. 6. The optic tectum exists as an ordered localization system, in the form of a topographical map. 7. Other selective neurons observed in the optic tectum include widefield arousal neurons, binocular neurons, and approach-sensitive neurons. 8. The LGN also receives some inputs from the optic tectum ( also known as the superior colliculus ). 9. The rest of the processing is similar to that of the visual sense and, thus, involves the optic tectum . 10. Information from multiple types of cues is used to create the map of elevation and azimuth in the optic tectum .
