What is the function of the colliculi?
The colliculus as a whole is thought to help orient the head and eyes toward something seen and heard. The superior colliculus also receives auditory information from the inferior colliculus. This auditory information is integrated with the visual information already present to produce the ventriloquism effect.
What reflexes does the inferior colliculi control?
Caudally directed projections of the inferior colliculus to the brainstem and spinal cord form part of the tectospinal and tectotegmental tracts. These projections are relatively small and probably mediate reflex turning of the head and eyes in response to sounds.
What is the role of superior colliculus?
The superior colliculus (SC) is a midbrain area where visual, auditory and somatosensory information are integrated to initiate motor commands. The SC plays a central role in visual information processing in the mouse; it receives projections from 85% to 90% of the retinal ganglion cells (RGCs).
What role does the superior colliculus play in vision?
The superior colliculus (SC) is a multisensory midbrain structure that integrates visual, auditory, and somatosensory spatial information to initiate orienting movements of the eyes and head toward salient objects in space.

What is the role of the inferior colliculus of the corpora Quadrigemina?
The inferior colliculus (IC) (Latin for lower hill) is the principal midbrain nucleus of the auditory pathway and receives input from several peripheral brainstem nuclei in the auditory pathway, as well as inputs from the auditory cortex.
What does the lateral geniculate nucleus do?
The lateral geniculate nucleus is a multilayered structure that receives input from both eyes to build a representation of the contralateral visual hemifield.
What is the role of the inferior colliculi of the corpora quadrigemina?
What are the functions of the corpora quadrigemina? SUPERIOR COLLICULI control reflexes of head & eyes in response to VISUAL stimuli. INFERIOR COLLICULI control reflexes of head & eyes in response to AUDITORY stimuli.
Which part of the brain controls heart rate?
The brain stem sits beneath your cerebrum in front of your cerebellum. It connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate and blood pressure.
What part of the brain controls temperature and pain?
Parietal lobe: The parietal lobes are found behind the frontal lobes, above the temporal lobes, and at the top back of the brain. They are connected with the processing of nerve impulses related to the senses, such as touch, pain, taste, pressure, and temperature.
Where are inferior colliculi located?
midbrain
The inferior colliculus is a part of the midbrain that serves as a main auditory (sound) center for the body. It acts as the channel for almost all auditory signals in the human body.

The primary area of the brain thought to be involved in saccadic eye movements. superior colliculus noun. The area of the brain thought to be involved in hand-eye coordination.
What is the function of the inferior mesenteric vein?
The jejunal vein from the second part of the small intestine
What is the function of the inferior frontal gyrus?
The inferior frontal gyrus contains Broca’s area, which is involved in language processing and speech production . The inferior frontal gyrus is highly convoluted and has three cytoarchitecturally diverse regions. The three subdivisions are an opercular part, a triangular part, and an orbital part.
