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

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

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]

whole bunch of ear hair fun huh?
