  2. 6. Neurotransmitter released after mild pain
  3. 7. Receptor cells that are involved with peripheral and night vision
  4. 9. Responsible for detecting the direction of tilt and amount of acceleration of the head
  5. 11. Theory that states each area along the basilar membrane of the cochlea only respond to a specific frequency
  6. 14. Structure of the auditory system of flesh and cartilage attached to the side of the head
  7. 16. Idea that states it is possible to flood the spinal cord with sensory information to decrease the perception of pain
  8. 18. Principle that states the receptors of the sensory system respond only to a small range of stimuli
  9. 21. Holds receptors that are specialized to respond only to pheromones
  10. 26. Theory that states we perceive color in terms of paired opposites

Down
  1. 1. One of the bones attached to the eardrum which transmits vibrations to the oval window
  2. 2. Highest sensitivity to all tastes due to large number of papillae near the tip of the tongue
  3. 3. 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
  4. 4. intensity of a sound wave
  5. 8. Sharpens contrasts to emphasize the borders of objects
  6. 9. The “what” pathway for vision that originates from V2 and extends to the temporal lobe
  7. 10. The point at which the optic nerve leaves the eye because it has no visual receptors
  8. 12. Send inhibitory messages which stop the retina from sending unnecessary messages to the brain
  9. 13. Tone deafness
  10. 15. Area of the retina that aids in detailed vision processing
  11. 17. Adjustable anatomy of the eye that helps the pupil focus on objects of various distances
  12. 19. Neurons with larger receptive fields evenly dispersed through the retina that best respond to moving stimuli

  14. 22. Perception of amplitude determined by the number of firing cells
  15. 23. Expectation of harm that actually causes feelings of pain, discomfort, or sickness
  16. 24. Protein substance that causes inflammation, which also magnifies response to nearby heat and pain receptors
  17. 25. Receptor cells that are involved with visual detail and color vision
  18. 27. Inability to recognize people’s faces
  19. 34. Anatomy of the eye in which light enters
