Superior colliculus
QuestionChoice
The lateral geniculate nucleus (LGN) is a paired structure located in the thalamus. The LGN serves as a key part of the primary visual pathway and plays a central role in the processing and relay of visual information from the eyes to the primary visual cortex in the occipital lobe.

QuestionChoice
The hypothalamus is a small region located at the base of the brain, just above the brainstem. It receives projections from the retina in one of the secondary visual pathways. It is involved in regulating the body's internal clock and circadian rhythms, which influence sleep-wake cycles, hormone secretion, and other daily patterns.

A 43-year-old female presents to the ophthalmology clinic. She has been finding it difficult to move her eyes, especially when redirecting her attention to new visual targets. She has also noticed she has been finding it difficult to maintain a steady gaze.

Which subcortical region in the brain is affected?
a
