Intermediate Occipital Lobe Quiz

Q1. How is the occipital lobe commonly separated from the parietal and temporal lobes on the superolateral surface?

• By the central sulcus alone
• By the lateral sulcus alone
• By an imaginary line from the parieto-occipital sulcus to the preoccipital notch
• By the collateral sulcus alone

Q2. Which region of the primary visual cortex represents the contralateral lower visual field?

• Lower bank in the lingual gyrus
• Upper bank of the calcarine sulcus in the cuneus
• Inferior frontal gyrus
• Precentral gyrus

Q3. Which region of the primary visual cortex represents the contralateral upper visual field?

• Superior frontal gyrus
• Upper bank in the cuneus
• Lower bank of the calcarine sulcus in the lingual gyrus
• Postcentral gyrus

Q4. Where is central or macular vision represented within the primary visual cortex?

• Within the insula
• Near the frontal pole
• At the central sulcus
• Near the occipital pole

Q5. Where is more peripheral visual field information represented in primary visual cortex?

• Inside the corpus callosum
• More anteriorly along the calcarine cortex
• Within the precentral gyrus
