Vision

3. the reduction in activity in one neuron by activity in neighboring neurons
4. theory suggesting we perceive color in terms of opposites
6. an impaired ability to perceive movement
9. type of neuron in the retina that receives input directly from the receptors
10. non-adjustable part of the eye that focuses light
13. inability to perceive color differences
19. type of neuron in the retina that receives input from the bipolar cells
22. inability to recognize objects despite otherwise satisfactory vision
23. adjustable part of the eye that focuses light
24. primary visual cortex
25. damage to this area leads to loss in color constancy
27. visual path in the parietal cortex that helps the motor system locate objects; the “where” path
28. 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
31. type of retinal receptor that contributes to color perception
32. the rear surface of the eye which is lined with visual receptors

1. statement that whatever excites a particular nerve always sends the same kind of information to the brain
2. prefix for large cell bodies with large receptive fields that are distributed evenly throughout the retina
5. type of retinal receptors that detect brightness of light
7. colored area of eye
8. the inability to recognize faces due to damage of several brain areas
11. type of cell that receives input from receptors and delivers inhibitory input to bipolar cells
12. ganglion cells located in the fovea of humans and other primates
14. area where axons from each eye cross to the opposite side of the brain
15. ganglion cell axons that exit through the back of the eye and continue to the brain
16. visual paths in the temporal cortex that are specialized for identifying and recognizing objects; the “what” path
17. an opening in the center of the iris where light enters
18. geniculate nucleus that receives incoming visual information
20. the ability to respond in limited ways to visual information without perceiving it consciously
21. prefix for small cell bodies with small receptive fields in or near the fovea
26. theory that the cortex compares information from various parts of the retina to determine the brightness and color for each area
29. cells that get information from bipolar cells; various types refine the input to ganglion cells
30. prefix for small ganglion cells that occur throughout the retina
