Across
  1. 1. Perception of the frequency of a sound wave related to how frequently nerves fire
  2. 2. Anatomy of the eye that helps the pupil focus that is not adjustable
  3. 7. Perception of amplitude determined by the number of firing cells
  4. 8. Idea that states it is possible to flood the spinal cord with sensory information to decrease the perception of pain
  5. 11. Responsible for detecting the direction of tilt and amount of acceleration of the head
  6. 12. Neurons with larger receptive fields evenly dispersed through the retina that best respond to moving stimuli
  7. 14. Tone deafness
  8. 15. Made up of axons of ganglion cells joining together
  9. 17. Protein substance that causes inflammation, which also magnifies response to nearby heat and pain receptors
  10. 20. The point at which the optic nerve leaves the eye because it has no visual receptors
  11. 21. Adjustable anatomy of the eye that helps the pupil focus on objects of various distances
  12. 22. Theory that states we perceive color in terms of paired opposites
  13. 25. Holds receptors that are specialized to respond only to pheromones
  14. 28. Number of compressions per second of sound measured in Hertz
  15. 30. Neurotransmitter released after mild pain
  16. 31. Expectation of harm that actually causes feelings of pain, discomfort, or sickness
  17. 32. Principle that states the receptors of the sensory system respond only to a small range of stimuli
  18. 33. Highest sensitivity to all tastes due to large number of papillae near the tip of the tongue
  19. 35. Theory that states each area along the basilar membrane of the cochlea only respond to a specific frequency
Down
  1. 1. Inability to recognize people’s faces
  2. 3. intensity of a sound wave
  3. 4. Receptor cells that are involved with peripheral and night vision
  4. 5. The “where” pathway for vision that originates from V2 and extends to the parietal lobe
  5. 6. Sharpens contrasts to emphasize the borders of objects
  6. 9. One of the bones attached to the eardrum which transmits vibrations to the oval window

  8. 13. Anatomy of the eye in which light enters
  9. 16. Frequent/constant ringing in the ear often produced by nerve deafness
  10. 18. Inability to recognize or see the whole form of objects despite otherwise satisfactory vision
  11. 19. The “what” pathway for vision that originates from V2 and extends to the temporal lobe
  12. 23. Chemicals released by an animal that affect the behavior of other members of the same species, especially sexually
  13. 24. Send inhibitory messages which stop the retina from sending unnecessary messages to the brain
  14. 26. 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
  15. 27. Area of the retina that aids in detailed vision processing
  16. 29. Receptor cells that are involved with visual detail and color vision
  17. 34. Structure of the auditory system of flesh and cartilage attached to the side of the head
