The superior colliculus is a mass of gray matter found in the tectum (roof) of the rostral midbrain. It is a paired structure that sits just posterior to the periaqueductal gray and anterior to the inferior colliculus. It plays a vital role in processing visual information and initiation of reflexive eye and head movements.
The superior colliculus is a paired structure of the dorsal midbrain and is part of the midbrain tectum. The two superior colliculi are situated inferior/caudal to the pineal gland and the splenium of corpus callosum.
The superior colliculus contributes to motor functions that orient the head and eyes toward or away from a stimulus. When head movement is restricted, the superior colliculi are involved in saccadic eye motion.
The primary function of the superior colliculus is to receive environmental stimuli directly from the retina and use that information to send signals which induce eye movements, gaze shifts, and head movements. The superior colliculus functions through each of its layers.
The superior colliculus is a layered, multi-sensory structure. Its upper layer receives visual signals from the retina of the eye, while the lower layers process multiple signals from...
The main function of the superior colliculus is to physically redirect the sensory structures of the head toward stimuli of interest. This behavior, termed orienting, allows the eyes, ears, and other organs to gather detailed information about external stimuli.
The superior colliculus (SC), one of the most well-characterized midbrain sensorimotor structures where visual, auditory, and somatosensory information are integrated to initiate motor commands, is highly conserved across vertebrate evolution.
