Across
- 3. non-adjustable part of the eye
- 5. theory that states that the spinal cord receives messages from pain receptors but also input from touch receptors and from axons descending from the brain
- 7. type of receptor cells that exist in the periphery of the retina & is involved in both peripheral & night vision
- 11. small rounded projections on the tongue that contain taste buds within the grooves
- 13. the combination of taste and smell
- 14. motion blindness
- 16. an opening in the center of the eye in which light enters
- 17. these neurons only respond when the whole visual scene expands, contracts, or rotates
- 21. the result of stimulation of taste buds
- 22. these neurons fire when an object moves relative to its background
- 23. a tiny area of the retina specialized for acute, detailed vision
- 24. a protein substance that causes inflammation
- 25. a condition that may result from damage to the inferior temporal cortex; it involves an inability to recognize objects despite otherwise satisfactory vision (cannot label objects)
- 31. the reduction of activity in one neuron by activity in neighboring neurons
- 32. types of neurons that have larger receptive fields & respond best to moving stimuli, evenly dispersed throughout the retina
- 34. expectation of harm actually causes feelings of pain, discomfort, or sickness
- 35. a nerve that is made up of ganglion cell axons and sends messages to the brain
- 36. type of cell that send inhibitory messages, which stop the retina from sending messages to the brain
- 37. the number of compressions per second of a sound, measured in hertz; pitch
- 38. chemicals released by an animal that affect the behavior of other members of the same species, especially sexually
- 39. area where axons from each eye cross to the opposite side of the brain
- 42. tone deafness; impairment in detecting small changes in frequency in sound
- 43. theory that states that the cortex compares the responses from different parts of the retina to determine the brightness of color
Down
- 1. the sense of smell
- 2. strong pain causes the release of this neurotransmitter
- 4. type of cell in the retina that receives input directly from the receptors
- 6. the rear surface of the eye which is lined with visual receptor cells
- 8. theory that states that we perceive any given color due to the ratio of activity across the three types of cones
- 9. mild pain causes the release of this neurotransmitter
- 10. types of neurons that have small receptive fields & respond best to visual details and color, located in or near the fovea
- 12. the intensity of a sound wave (loudness)
- 15. a band of tissue that gives eyes their color
- 18. the point at which the optic nerve leaves the eye because it has no visual receptors
- 19. a set of receptors located near, but separate from, the olfactory receptors
- 20. a blurring of lines in one direction; this disorder is caused by an asymmetric curvature of the eyes
- 26. therory that states that we perceive color in terms of paired opposites
- 27. types of cells that are important for complex processing & refine information that is sent to ganglion cells
- 28. types of neurons that are small but are found throughout the retina and respond to many types of stimuli
- 29. the ability to respond in some way to visual information after extensive damage to area v1
- 30. a condition where the effected individual cannot identify the person (fusiform gyrus is damaged)
- 33. adjustable part of the eye
- 38. a drug that has no pharmacological effects but often relieve pain due to the power of belief
- 40. structures on the tongue that contain receptor cells
- 41. type of receptor cells that are involved in both visual acuity & color vision
