CHAPTER 4.21: Frequency Theory

Question 1

why do we need frequency theory?

Answer 1

bc place theory breaks down at very low frequencies since they end up at the same PLACE in the basilar membrane.

Question 2

what is frequency theory

Answer 2

hair cells independent of their location can signal something about the frequency of sound

Question 3

if we have a 20Hz wave, how many times will wave cells fire?

Answer 3

20

Question 4

what is the upper limit that an individual hair cells can communicate?

Answer 4

1000 Hz

Question 5

how can brain get around the hair cell upper limit of signalling

Answer 5

volley principle!

Question 6

what is the volley principle

Answer 6

to get around the issue of hair cell refractory periods, the brain sums the responses of a group of cells to get a more accurate representation of frequency
