A patient experiences a stroke that results in damage to the superior colliculus. Which of the following functions would most likely be impaired?

A Conscious perception of touch
B Voluntary fine motor control of the hands
C Reflexive eye movements to visual stimuli
D Auditory processing and localization

✓ Correct Answer: Option C

The superior colliculus is a midbrain structure crucial for orienting the head and eyes towards visual stimuli. Damage would impair reflexive saccadic eye movements and visual tracking, not conscious perception or fine motor control.
