Question

15. Cortical Processing of visual information is primarily performed in the Primary Visual Cortex within the Occipital Lobe, but there are also Visual Association Areas within the Temporal, Parietal, and Frontal Lobes is this true?

19. The Lateral Genticulate Nuclei of the Thalamus receive visual sensory information from the optic nerve, is this true?

Answer 1

15)

False

• It is true that , Cortical Processing of visual information is primarily performed in the Primary Visual Cortex within the Occipital Lobe, but visual  Association Areas are located in the occipital lobe and not in the temporal , parietal and frontal lobes.
• Visual association cortex includes the entire medial surface of the occipital lobe beyond the primary area and lateral surface of occipital lobe.( areas 18 and 19).
• Visual cortex is the part of cerebral cortex , which processes visual information.
• Visual association area surround the primary visual cortex.

19)

True

• In the visual system , thalamus recieve input from retina , which is relayed to brain via optic nerve.
• Signals are sent to lateral geniculate nucleus of thalamus , which then forward them onto the primary visual cortex ( area V1 in the occipital lobe.)
• Lateral geniculate nucleus is also called lateral geniculate body is a relay center in thalamus for the visual pathway.
• Optic nerve is the nerve wich transmit visual information from retina to the brain.
