Which of the following is a reason for motion processing occurring at multiple stages in the brain?
Which of the following is a reason for motion processing occurring at multiple stages in the brain?
- To complicate the perception of motion
- To solve the aperture problem effectively (correct)
- To eliminate the need for global motion detectors
- To introduce ambiguity in motion perception
What does the presence of distinct populations sensitive to local and global motion imply?
What does the presence of distinct populations sensitive to local and global motion imply?
- That local motion is the only important aspect of motion perception
- That global motion is irrelevant in visual processing
- That different scales of motion require different processing (correct)
- That motion detectors are unnecessary for perception
Where are global-motion detectors likely to be located in the brain?

- Lesions in the parvocellular layers of LGN
- In the superior colliculus
- In the M pathway of the LGN (correct)
