Cochlear animation

[LilyMagick666]

This was such a fun video to watch and also very helpful for us audiology students! Thanks for posting this.

[201ZEN]

Nice vibrato.

XD



[battheman777]

It would be a good idea to supplement your title by including basilar membrane in some fashion. Otherwise, great vid. Thanks for the post.

[Karimaq16]

Awesome!



[beeflin]

wow I have an internal synthesiser keyboard!

[TheBobsmithers]

hahahah hilarious. at the end it was like 'fuck the auditory system, lets just break out this sweet ass solo'

[Gemm6905]

Perfect! Just what I needed to finally understand how exactly the basilar membrane works. Kind of. I think. Argh, hell...

[pogonish]

note that this animation disregards the nonlinear effects. the cochlea does not simply perform a spectral analysis.

[xxmisaxx8]

not VERY helpful :(

[eresimbecil92]

really helpful…

[FlashySenap]

Does it mean that the inner part of the ear recognize lower pitch noise while the outer parts recognize the lower pitch noises?

[Psylence6]

@FlashySenap Almost! The Base of the cochlea (closest to the external ear) transduces high frequency sounds, while the Apex of the cochlea (other end) transduces low frequency sounds.

[BabyShelly20]

@Psylence6 the area closet to the external ear is near the stapes and at the apex of the cochlea this is the helicotrema

[MedPiment]

gratz man

[BrotherLord73]

Mmm you right that why cochlear got 22 channel become sound frequency low & high. I can't wait get cochlear.

This is video so simple to understand how is work...

Thanks

its Fugue by Bach

[channingwalton]

actually, although the toccata and fugue in d minor is attributed to JS Bach, there is some academic debate as to whether he really wrote it.

[Megahead94]

i like that song wats it called?

[ozgribbo]

@Megahead94 Toccata & Fugue in d minor (BACH, J.S.)

[Xyfrag]

@Megahead94 toccata & fugue

[SourRevenge]

@Megahead94 Toccata and Fugue by Bach :]

Great animation, but someone correct me if I'm wrong - I think it's a little inaccurate. The thickest part of the basilar membrane is at the apex (or helicotrema) and the thinnest part is at the base- this video makes it look like the base is thicker- which doesn't make sense because it resonates at high frequency. I believe it should be thin at the base and resonant at high frequency - so you just have to flip the thick/thinness - but the resonant regions are accurate. Sorry to be so picky...

[ellierachael]

i've been doing this in a biomedical science module at university, although it seems not to make sense the base is the widest part and it is tuned to the lower frequencies, even though logically you would think it was the other way around

[smpsnow]

The base does hear HIGH frequency sound best, while the helicotremia responds to LOW frequency sound best. So your gut logic was right, the base is NOT tuned to lower frequencies. But since you wrote this 3 weeks ago I bet you have figured that out by now :)

[GeorgiosMICHALAKIS]

@ellierachael If one watches the cochlea being rolled out (0:14), the BASE is to the LEFT whereas the "apex" is to the RIGHT, with their respective HIGH and LOW pitch vibration/detection zones. Now, although most "rolled out basilar membrane" diagrams I have seen show the apex as being slightly wider, I'd be interested in their REAL width dimensions (to dissipate any confusion with "parallax effect") as well as those of the overall outer core.

[awakenedhope646]

you know what? you're absolutely right. they did it backwards. The base here is responding to low frequency and the apex is responding to the high frequency. It should be the other way around.

[Splengie]

@awakenedhope646 no. watch when it rolls out. the apex is to the left.

[Splengie]

@Splengie *right

[jelsbells]

it resonates at a high frequency because its more taut, not because its thinner or thicker.

[Splengie]

@jelsbells incorrect

[SunnyRaeAllen]

i love how intricate and amazing the human body is. The big bang...ha.

[bmd1889]

Is this exhibiting the Place Theory for sound?

[lisachan459]

what you're actually watching is the basliar membrane in the cochlea =)

[extremecalling]

This is so awesome!!! I really enjoyed being able to watch exactly what was happening in my own ear while I listen to Bach/watched this video. Thanks so much! ^_^

[TehEddShow]

the cochlea looks like a whip to me hahahaha.

[kristiano023]

yeah love the cochlear

[GalliumGnu]

That was neat!

[sirfreakman]

ho ho ho awesome

[mikkiemuis81]

Cool!! tenks,
