Across
  1. 1. the CN is highly responsive to what kind of tones?
  2. 3. In the DCN, these structures help sharpen the edges of tuning curves so there is sharper tuning at lower intensities than higher intensities
  3. 4. these fibers leave along the ventral acoustic stria
  4. 6. neurotransmitters in CN that are inhibitory
  5. 9. these fibers exit via the intermediate acoustic stria
  6. 11. these output fibers course along the dorsal stria
  7. 13. The dorsal, intermediate, and ventral stria are the 3 primary routes of ___ _____
  8. 16. these AN fibers project to the lateral regions of the ____ _____
  9. 17. this is a crude hearing screening that tests what your response is when you hear a very loud sound. It has a latency of 10-15 msec. AN and CN are main players in this reflex
Down
  1. 1. neurotransmitter in CN that is inhibitory and excitatory depending on location
  2. 2. these type of AN fibers project to the lateral portions of the DCN and PVCN
  3. 5. this structure is thought to contribute to the generation of wave 3 in ABR
  4. 6. neurotransmitters in the CN that are excitatory
  5. 7. the CN is ________ organized, just like the cochlea
  6. 8. high frequency AN fibers project to the ____ and ____ regions of the AVCN
  7. 10. as intensity increases, there is what kind of increase in the firing rate of most cells within the CN?
  8. 12. tuning curves of the CN vary by __ ____
  9. 14. In the CN, there is a dynamic range of _____ for most fibers (some up to 90 dB)
  10. 15. after processing is completed in the CN, neural impulses travel to other nuclei along the auditory pathway on both sides of the brainstem. This is known as the first level of _____ in the CANS
  11. 18. low frequency AN fibers project to the ____ and _____ portions of the AVCN
