Across
  1. 3. The “stirrup;” one of the bones of the ear
  2. 4. The entrance to the ear canal
  3. 5. colliculus This receives bilateral innervation from the LSO, as well as indirect input from the CN via the lateral lemniscus
  4. 8. cortex This receives input primarily from the contralateral ear via the ipsilateral MGB
  5. 11. Resistance to the flow of energy
  6. 13. The bones of the ear are collectively known as this
  7. 15. membrane This marks the boundary between the outer and middle ear
  8. 16. of light This area that reflects the lights of an audiologist’s otoscope
  9. 19. of Corti This separates the outer and inner hair cells
Down
  1. 1. In this type of response, there is an initial response to the start of a stimulus followed by silence
  2. 2. These take longer to respond than other neurons, having an initial on-response for strong stimuli
  3. 4. 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
  4. 6. A device used to view cavities of the body
  5. 7. Inflammation of the mastoid bone
  6. 9. The rate of firing increases because this increases
  7. 10. These neurons slowly increase their firing rate through the initial stages of firing
  8. 12. This is lateral to the belt and makes up the third level of processing of the input auditory signal at the reception area
  9. 14. Excitation of the inner hair cells occurs primarily as a result of this effect on the cilia
  10. 17. ear Houses the sensors for balance and hearing
  11. 18. The curled margin of the pinna
