Vision
1. What are three important components of a hypercolumn in primary visual cortex?
Ocular dominance columns
Orientation selective columns
blobs
2. Draw a diagram that explains how a complex cell in visual cortex can respond to a moving bar
of light. Think about hierarchical organization.
3 simple cells:
1 2 3
- + - - + - - + -
- + - - + - - + -
- + - - + - - + -
Motion-sensitive complex cell

3. The figure above shows sites (black bars) at which that part of the visual pathway has been
damaged. For the locations A, B and C, indicate which part of the visual field (nasal, temporal,
both or neither) of both the left and right eye is affected by the damage. Use shading to indicate
which parts of the visual field are blinded.
