slide8
Ch 6

7. Hubel and Wiesel found that several neurons encountered along a(n) _______ electrode tract in the primary visual cortex had receptive fields in the same general area of the visual field and preferred straight line stimuli in the same orientation.

  • oblique
  • straight
  • vertical
  • horizontal
slide9
Ch 6

8. The ventral visual stream has been referred to as the _______ pathway, which flows from the primary visual cortex to the ventral prestriate cortex and finally to the ________ cortex.

slide10
Ch 6

9. Because of the phenomenon of color constancy, the color of an object_______.

Ch 6

10. The retinal ganglion cells _______.

  • are responsible for scotopic vision only

slide12
Ch 6

11. The retina-geniculate-striate system________.

slide13
Ch 6

12. cones are to rods as________.

slide14
Ch 6

13. The M pathway for visual information is ________.
