- 26. Area where the optic nerve sends information from the right eye to the left hemisphere and vice versa
- 29. Receptor cells within the taste buds
- 30. Chemicals released by an animal that affect the behavior of other members of the same species, especially sexually
- 32. Provides 70% of the input to the brain
- 34. Middle ear deafness
- 36. Power of belief that relieves pain when given a drug with no pharmacological effects
- 37. Number of compressions per second of sound measured in Hertz
- 39. “Where” pathway that helps determine where sounds originate
- 40. Type of neuron in the retina that receives input directly from the receptor
- 43. Receptor cells that are involved with peripheral and night vision
- 44. Neurotransmitter released after mild pain
- 45. Respond to the stretching of the skin
- 46. The point at which the optic nerve leaves the eye because it has no visual receptors
- 48. Respond to light touch
- 49. intensity of a sound wave
- 50. Responsible for detecting the direction of tilt and amount of acceleration of the head
- 52. The “where” pathway for vision that originates from V2 and extends to the parietal lobe
- 53. Inability to recognize or see the whole form of objects despite otherwise satisfactory vision
- 55. Protein substance that causes inflammation, which also magnifies response to nearby heat and pain receptors
Down
- 1. Frequent/constant ringing in the ear often produced by nerve deafness
- 3. Inner ear deafness
- 5. Neuropeptide released after strong pain
- 6. Sharpens contrasts to emphasize the borders of objects
- 7. Eardrum, vibrates at the same frequency as the sound waves that strike it
- 10. Theory that states we perceive color in terms of paired opposites
- 11. Area of the retina that aids in detailed vision processing
- 12. Theory used to explain how the retina determines the brightness of color
- 17. Neurons with small receptive fields in or near the fovea that best respond to visual details and color
- 19. A nerve excited by a particular type of energy generates a specific energy unique to that nerve
- 20. The “what” pathway for vision that originates from V2 and extends to the temporal lobe
- 22. Adjustable anatomy of the eye that helps the pupil focus on objects of various distances
- 24. Rapid eye movements that detect subtle changes from millisecond to millisecond
- 27. Principle that states the receptors of the sensory system respond to a wide range of stimuli and contribute to the perception of each of them
- 28. Anatomy of the eye that helps the pupil focus that is not adjustable
- 31. One of the bones attached to the eardrum which transmits vibrations to the oval window
- 32. Neurons with larger receptive fields evenly dispersed through the retina that best respond to moving stimuli
- 33. Theory that states there are three types of cones that respond to certain wavelengths
- 35. Able to see objects but impaired at seeing whether they are moving
- 38. Send inhibitory messages which stop the retina from sending unnecessary messages to the brain
- 41. Chemical that releases energy when struck by light
- 42. Highest sensitivity to all tastes due to large number of papillae near the tip of the tongue
