The superior colliculi are two small, paired structures located on the dorsal side of the midbrain. They play a crucial role in visual processing and are involved in coordinating eye movements and visual attention. The superior colliculi help integrate sensory information, allowing organisms to respond quickly to visual stimuli. In addition to their visual functions, the superior colliculi are also involved in reflexive movements, such as turning the head toward a stimulus. They receive input from various sensory modalities, including vision, auditory, and somatosensory systems, making them important for orienting responses to the environment.
