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
what supplies the PVC (primary visual cortex) - ✔✔✔ Correct Answer
> PCA
If there is a lesion in the temporal area, what optic radiations will it
affect? Causing what? - ✔✔✔ Correct Answer > a. Inferior fibers
b. Contralateral superior quadrantanopia aka pie in the sky
If there is damage to the parietal lobe, what optic radiation will it
affect? Causing what? - ✔✔✔ Correct Answer > a. Superior optic
radiations
b. Contralateral inferior quadrantanopia aka pie on the floor
,what does the superior and inferior colliculi form - ✔✔✔ Correct
Answer > it forms the tectum roof
the floor of the fourth ventricle contains bumps that are visible, what
are they called - ✔✔✔ Correct Answer > facial colliculi
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
