HUS2-50 Vision II: visual pathways

Where do signals from the upper temporal visual field of left eye project to?

• Upper gyrus of right calcarine sulcus

• Lower gyrus of left calcarine sulcus

• Left LGN

• Right LGN

• Upper temporal retinal quadrant of the right eye

What layers of LGN receive ipsilateral retinal inputs?

• 1,3,5

• 2,4,6

• 1,3,6

• 1,4,6

• 2,3,5

The optic tract is located at

• medial surface of diencephalon

• lateral surface of diencephalon

• inferior surface of diencephalon

• V1 (area 17)

• V4 (area 19)

Which of the following about where the medial root of optic tract projects to is correct?

• It projects to suprachiasmatic nucleus to regulate circadian rhythms

• It projects to the pretectum to orientate the movement of head and eyes

• It projects to the superior colliculus for pupillary light reflex

• It projects to the PPRF for visual attention and motion perception

• It projects to the PPRF for coordination of vertical gazes

Optic Radiation are axons from neurons in LGN to V1, and Meyer's loop travels around the

• third ventricle

• fourth ventricle

• anterior horn of lateral ventricle

• posterior horn of lateral ventricle

• inferior horn of lateral ventricle

Which of the following about the retinotopic map is correct?

• Central to peripheral axis in the visual field is represented postero-anteriorly in Area 17.

• 10 is represented larger than 4 on opposite sides.

• 2 is represented to V1 on the left posterior side, below calcarine fissure.

• 2 is represented to V1 on the left posterior side, above calcarine fissure.

• 2 is represented to V1 on the right anterior side, above calcarine fissure.

Which of the following regarding pathways in higher visual centers is correct?

• Pathway for motion, depth and dynamic form perceptions is also known as the temporal pathway.

• In "what" pathway, layer 2,3 in V1 receives inputs from parvocellular layers of LGN, then projects ventrally to V2, V4.

• In "where" pathway, layer 2,3 in V1 receives inputs from magnocellular layers of LGN then projects ventrally to V2, V3, V5.

• When viewing color object, middle temporal gyrus (MT or V5) in

  the lateral temporal area is most active.

• The primary visual cortex is V1-V2, while V3-V5 are visual association cortices.

Which of the following about area 37 is correct?

• It is located in the retinotopic cortex.

• It is medial to the areas for color vision in the ventral pathway

• It is rostral to the Wernicke's area.

• It is contains fusiform gyrus, and area for facial recognition.

• It is located in the infratemporal fossa.

This is the worldview of a patient, who has a cerebral lesion. Where is the lesion most likely located?

• bilateral lesion in V4

• left side lesion in V4

• right side lesion in area 19

• left side lesion in V2

• left side lesion in area 17
