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