Questions and Answers

Which pathway in the visual cortex is important for identifying and recognizing objects?

  • Secondary visual cortex
  • Ventral stream (correct)
  • Primary visual cortex
  • Dorsal stream

    • What type of information does the dorsal stream pathway in the visual cortex process?

  • Identifying objects
  • Recognizing objects

  • Trouble integrating vision with arm and leg movements
  • Difficulty in identifying objects (correct)
  • Difficulty in visually guided movement
