visual reflex

One possibility is that they provide inputs for very specific visual reflexes.

The tectum is responsible for auditory and visual reflexes.

Clearly, information from the subcortical visual system can, under some circumstances, be used for more than the control of visual reflexes.

There is good evidence that visual reflexes retained after visual cortex ablation are lost after subcortical lesions.

Descending fibers can also arise from the superior colliculus in the rostral midbrain for visual reflexes, the accessory occulomotor nuclei in the rostral midbrain for visual tracking, and the pontine reticular formation, which facilitates extensor muscle tone.
