Neuroanatomy: Pupillary and Visual Reflexes

In the pupillary light reflex, what is the primary reason for the consensual response occurring simultaneously with the direct response?

Why can the pupillary light reflex be used to test for brainstem death in unconscious patients?

During the accommodation reflex, which sequence of actions allows the eye to focus on a near object?

In the corneal reflex, if the ophthalmic division of the trigeminal nerve (CNV1) is damaged on the left side, what would be the most likely outcome when the left cornea is stimulated?

What is the most likely immediate effect of decreased light exposure on the pupil, and what neurological pathway initiates this response?

Which of the following best describes the path of visual information from the retina to the visual cortex?

The optic chiasm is crucial for visual processing because it is where:

Why is the fovea important for vision?

Damage to the lateral geniculate body (LGB) would most likely result in:

What is the role of bipolar cells in the retina?

How does the visual cortex receive information ensuring that each hemisphere processes the contralateral visual field?

If a lesion ONLY affects Meyer's loop on the right side of the brain, which visual field defect would most likely result?

A patient presents with a lesion at the optic chiasm that selectively damages only the crossing fibers. Which specific visual field deficit would be expected?

Damage to the lower wall of the calcarine sulcus in the left hemisphere would result in a visual field defect in which specific region?

Information from the right visual field is processed:
