What is an excellent colliculus?

Superior Colliculus is a set of two bumps on the dorsal side of Midbrain. The larger area, optical tectum, consists of this structure and lower colliculus. Sometimes the superior Colliculus is simply referred to as Tectum. Unlike Lower Colliculus, which is involved in hearing, TECTUM plays a role in vision processing.

This structure is connected to visual reflexes. The visual bark and the retina itself project information about the outer layers of the TECTUM. The middle layers also receive sensory input from visual and auditory neurons, as well as inputs from motor centers. The deepest layers are given mainly the engine input and can even control the movement of the eyes and other motor events. This wide range of input types helps to move this structure with head and eyes towards sensory stimuli. This representative map is aligned with retinal cells. Functional enables activation of different retinal cells and triggers the corresponding response on the map. Tectum can then navigate the eyes and head in the same direction ashave appeared.

To achieve orientation movements, the superior Colliculus sends a connection from its deeper layers to the cervical backbone. These projections spread to the cervical cord and walk through the brain on their way. The signals sent in this way help the body to navigate the neck and head in the direction of stimuli. It will not only cause visual stimuli to this orientation reflex. This path is also activated by auditory and somatosensory or touch stimuli.

Medium and deep neurons also send motor projections directly to the eyes. The visual signals from the right side of the retina cross to the left hemisphere of the brain. There is a similar crossover with Superinebo Colliculus's eye control. The cells in the left tectum will navigate the movement of the eyes to the right.

Eye movement and eye orientation are the main reactions that this structure controls in human beings, along with some arm movements. Other animals have their ownIt owns unique reflective behavior, which is also controlled by TECTEM. The frogs use this structure to quickly direct the tongue to capture the prey, and the rats can turn all their bodies based on tectal activity. People have the main cortical areas that expand visual and motor centers, and therefore this structure is not as large as other species.
