00:04

And here's your shmoop du jour brought to you by different tones

00:06

what your mom asks you to use when she's not appreciating your sarcasm well [Mom shouting at son]

00:11

here's today's question the theory of hearing that suggests that we hear

00:14

different tones due to where the hair cells are located in the cochlea is

00:18

called the what and here are your potential answers.... well right

00:25

off the bat we can go ahead and eliminate E) Basilar theory that's not

00:29

even a real thing creativity is great and everything but maybe not in a [Man painting]

00:32

multiple choice test taking scenario so save that for art class people how about

00:36

option A) well it's got one thing going for it opponent process theory is a real

00:41

thing it suggests that there are certain combinations of colors that one never [red and blue button with smiley and crying faces]

00:45

sees together at the same time in place think about it we can definitely see

00:48

yellowish greens and bluish reds, like these but what about reddish greens or

00:53

yellowish blues? well, these colors are considered impossible colors made [greenish red and yellowish blue colors]

00:58

impossible by the way in which the perceptive cones in our eyes sometimes

01:02

oppose one another cool definitely related to hair cells definitely not so [A digram of a hair cell]

01:09

we can cross out A) let's check out D) gate-control theory developed in the

01:14

1960s the gate-control theory of pain says that non painful stimulus can close [people walking through a door labelled central nervous system]

01:19

the gate to painful input preventing the pain sensation from reaching the

01:23

central nervous system the idea is that large nerve fibers in the spinal cord [a spinal cord]

01:29

stimulated by non painful stimulation can activate in blocks of small fibers

01:33

that would typically communicate with the sensation of pain also pretty cool [person hearing soundwaves]

01:37

but it doesn't have to do with hearing so it's not our answer so take D) out

01:42

could our answer be C) temporal theory well temporal theory suggests that how we [girl listening to music on a field]

01:48

perceive sound depends on the temporal patterns in which the neurons in our

01:53

cochlea respond to the sound.. In other words the pitch of sound is an attribute [Person whispering in a girls ear]

01:57

that is perceived not a physical property of the stimulus and the way in

02:02

which we perceive the pitch is dependent on the timing of the firing of the nerve [Arrow points to nerve in the brain]

02:05

impulses from within our ear hmmm close but no cigar this definitely has to do

02:11

with the basilar membrane within the cochlea [arrow pointing to cochlea in an ear]

02:14

the hair cells it contains but it doesn't have anything to do with the

02:16

placement of those cells so C) can see its way out of the scene that leaves us

02:22

with B) place theory, place theory differs from temporal theory in one

02:27

major way it suggests that the way in which we interpret pitch has to do with [Man talking on a cell phone]

02:32

the placement of the hair cells in the cochlea but once it sound hits the

02:36

eardrum it initiates a transfer of vibrations into the cochlea this [vibrations travelling down the ear]

02:39

vibration determines which hair cells move along the basilar membrane and as

02:43

the theory goes where a hair cell is located determines the frequency that

02:48

any given cell will detect the perceived pitch then is determined by which parts [Person making noise and sound waves travel]

02:53

of the membrane the initial sound eventually causes to vibrate that means

02:57

B) is the correct answer now every time you hear music you get to imagine a [A couple listening to music with headphones]

03:01

whole bunch of ear hair fun huh?
