Final answer:

Visual information is relayed to the cortex via the lateral geniculate nucleus after passing through the optic nerve, optic chiasm, and optic tract.

Step-by-step explanation:

Before reaching the cortex, visual information is relayed through the lateral geniculate nucleus (LGN). After passing through the optic nerve and optic chiasm, the visual signal travels along the optic tract and arrives at the LGN of the thalamus. From there, axons project the visual signal to the visual cortex located in the occipital lobe of the brain. Additionally, visual signals are also sent to the superior colliculi and the suprachiasmatic nucleus (SCN) for further processing involved in eye movements and circadian rhythms.
