Across
  1. 4. Excitation of the inner hair cells occurs primarily as a result of this effect on the cilia
  2. 7. This is lateral to the belt and makes up the third level of processing of the input auditory signal at the reception area
  3. 9. In this type of response, there is an initial response to the start of a stimulus followed by silence
  4. 10. of Corti, This separates the outer and inner hair cells
  5. 12. Resistance to the flow of energy
  6. 13. membrane, This marks the boundary between the outer and middle ear
  7. 16. The rate of firing increases because this increases
  8. 18. cortex, This receives input primarily from the contralateral ear via the ipsilateral MGB
  9. 19. This type of response does not seem to be related to stimulus frequency, but appear to have a periodic, chopped temporal pattern as long as a tone is present
  10. 20. These neurons slowly increase their firing rate through the initial stages of firing
Down
  1. 1. The “stirrup;” one of the bones of the ear
  2. 2. of light, This area that reflects the lights of an audiologist’s otoscope
  3. 3. The bones of the ear are collectively known as this
  4. 5. Inflammation of the mastoid bone
  5. 6. ear, Houses the sensors for balance and hearing
  6. 8. colliculus, This receives bilateral innervation from the LSO, as well as indirect input from the CN via the lateral lemniscus
  7. 11. These take longer to respond than other neurons, having an initial on-response for strong stimuli
  8. 14. The entrance to the ear canal
  9. 15. The curled margin of the pinna
  10. 17. A device used to view cavities of the body
