Across
- 2. damage to this area leads to loss in color constancy
- 4. cells that get information from bipolar cells; various types refine the input to ganglion cells
- 5. prefix for small ganglion cells that occur throughout the retina
- 7. an opening in the center of the iris where light enters
- 8. ganglion cells located in the fovea of humans and other primates
- 9. prefix for large cell bodies with large receptive fields that are distributed evenly throughout the retina
- 10. inability to perceive color differences
- 13. primary visual cortex
- 18. statement that whatever excites a particular nerve always sends the same kind of information to the brain
- 21. type of retinal receptor that contributes to color perception
- 22. type of neuron in the retina that receives input directly from the receptors
- 23. the ability to respond in limited ways to visual information without perceiving it consciously
- 25. theory that the cortex compares information from various parts of the retina to determine the brightness and color for each area
- 26. visual path in the parietal cortex that helps the motor system locate objects; the “where” path
- 29. prefix for small cell bodies with small receptive fields in or near the fovea
- 30. an impaired ability to perceive movement
Down
- 1. non-adjustable part of the eye that focuses light
- 2. inability to recognize objects despite otherwise satisfactory vision
- 3. thalamic nucleus that receives incoming visual information
- 6. ganglion cell axons that exit through the back of the eye and continue to the brain
- 11. colored area of eye
- 12. area where axons from each eye cross to the opposite side of the brain
- 14. type of retinal receptors that detect brightness of light
- 15. theory that color is perceived through the relative rates of response by three kinds of cones, each on maximally sensitive to a different set of wavelengths; also called Young-Helmholtz theory
- 16. the inability to recognize faces due to damage of several brain areas
- 17. visual paths in the temporal cortex that are specialized for identifying and recognizing objects; the “what” path
- 18. the reduction in activity in one neuron by activity in neighboring neurons
- 19. theory suggesting we perceive color in terms of opposites
- 20. type of neuron in the retina that receives input from the bipolar cells
- 24. type of cell that receives input from receptors and delivers inhibitory input to bipolar cells
- 27. the rear surface of the eye which is lined with visual receptors
- 28. adjustable part of the eye that focuses light
