The superior colliculi control which of the following functions?

• A. Regulation of heart rate and blood pressure
• B. Auditory processing and sound localization
• C. Balance and coordination of voluntary movements
• D. Visual reflexes and coordination of eye movements

Answer: (D)

Verified step by step guidance

1. Identify the location of the superior colliculi in the brain. They are part of the midbrain, located on the dorsal aspect of the brainstem.
2. Understand the primary function of the superior colliculi. They are involved in processing visual information and coordinating eye movements.
3. Differentiate the functions of the superior colliculi from other brain structures. For example, the inferior colliculi are involved in auditory processing, while the cerebellum is responsible for balance and coordination.
4. Recognize that the superior colliculi are part of the tectum, which is involved in visual reflexes, such as tracking moving objects and orienting the eyes and head towards visual stimuli.
5. Conclude that the superior colliculi are primarily responsible for visual reflexes and coordination of eye movements, distinguishing them from functions related to heart rate, blood pressure, or auditory processing.
