Answer: The superior colliculus
Explanation: The ability of a mammal to orient it's eyes (eye movement) to an object of interest is the responsibility of the superior colliculus which is a part of the visual structural system located in the mid brain of mammals. They are charged with the transformation of sensory input(visual) from the retina into movement output (eye movement). Once a visual element or input is captured by the retina or certain commands in the cerebral cortex, this serves as the input command or sensory input, if the strength of the input is adequate, it results in an eye movement in other to catches a glimpse of the input, The superior colliculus is most likely responsible for this movement.
