What pathway is it when a minority of fibers in the optic tract
bypass the LGN to enter the superior colliculi and pretectal
areas? - ✔✔✔ Correct Answer > Extrageniculate pathway
In the Extrageniculate pathway, after the info projects the
superior colliculus, where does the info go? - ✔✔✔ Correct
Answer > Association cortex via the pulvinar
Axons that leave the LGN will project to where and through
what? - ✔✔✔ Correct Answer > Primary visual cortex through
the optic radiations
L optic radiation will contain R/L fibers from R/L visual fields of
one or both eyes? - ✔✔✔ Correct Answer > L fibers
R visual field
both eyes
