After the neural signals from each visual field separate at the optic chiasm, the majority of the neurons from the optic nerve travel to the:
A)superior colliculus, while 10% travel to the lateral geniculate nucleus in the thalamus
B)left visual cortex, while 10% travel to the right visual cortex
C)lateral geniculate nucleus in the thalamus, while 10% travel to the superior colliculus
D)right visual cortex, while 10% travel to the left visual cortex

The majority of the neurons from the optic nerve travel to the lateral geniculate nucleus in the thalamus, where they synapse with neurons that project to the primary visual cortex. About 10% of the neurons from the optic nerve project to the superior colliculus, which is involved in generating eye movements and directing attention. Therefore, choice C is the best choice as it correctly identifies the destination of the majority of the neurons from the optic nerve.
