). In hagfish, lamprey, and shark it is a relatively small structure, but in teleost fish it is greatly expanded, in some cases becoming the largest structure in the brain. (See the adjoining drawing of a codfish brain.) In amphibians, reptiles, and especially birds it is also a very significant component, but in mammals it is dwarfed by the massive expansion of the cerebral cortex. Part of the midbrain tecturm consisting of paired bodies that sit caudal to the thalamus and surround the pineal gland in the mesencephalon of vertebrate brains. It comprises the rostral aspect of the midbrain, posterior to the periaqueductal gray and adjacent superior the inferior colliculus. The inferior and superior colliculi are known collectively as the corpora quadrigemina (Latin, quadruplet bodies). It consists of several identified cellular layers and also comprises the brachium of the superior colliculus and commissure of supeior colliculus from Wikipedia.org and Neuronames (MM). |

The term SC is used when discussing mammals, and OT for other vertebrates[WP] The tectum is a layered structure, with a number of layers that vary by species. The superficial layers are sensory-related, and receive input from the eyes as well as other sensory systems.[1] The optic tectum is one of the fundamental components of the vertebrate brain, existing across the full range of species from hagfish to human.[4] (See the brain article for background.) Some aspects of the structure are very consistent, including a structure composed of a number of layers, with a dense input from the optic nerve to the superficial layers and another strong input conveying somatosensory input to deeper layers. Other aspects are highly variable, such as the total number of layers (from 3 in the African lungfish to 15 in the goldfish[5]), and the number of different types of cells (from 2 in the lungfish to 27 in the house sparrow[5] |
