. Visual System

Question 1

Explain what is meant by the “easy” and “hard” problems of consciousness, and how these intersect with quantum theory (in a very general sense!)

Question 2

Define the phrase “neuronal correlates of consciousness”

Question 3

Review eye anatomy

Question 4

Explain how photoreceptors respond to light with a graded change in membrane potential

Question 5

Describe the organization and basic function of horizontal cells, amacrine cells, and Müller cells in retinal processing

Question 6

Explain how receptive field center on/off mapping of visual units is specialized for detection of contrast and movement

Question 7

Review the various targets of retinal signaling (not just the LGN!)

Answer 7

LGN
SCN
pre-tectal nucleus
pulvinar
superior colliculus

Question 8

Describe the neuroanatomy of the visual system from retina to thalamus to visual cortex, noting how fibers traveling in the system correspond to photons sensed in the visual and retinal fields

Question 9

Predict the effects of lesions to the visual system (visual field defects) at different points along the system
