dancing hair cell

[therampantbookworm]

If this hair cell was at a party...it would be the nerd in the corner bobbing awkwardly

[flamingpeach10]

I watched this at school give more info on the ear :)

[Bjelor]

i actually hoped the shit to do moonwalk and stuff

oh well...

[bandimko]

In this video we can see what Prestin protein is capable of! :)

So funny!

And interesting :)

[TheGanstaben]

even singlecellular beings likke this song

[TheMonkey96b]

now i know that when i jumpstyle

im not the only one dancing

[Spuffy24]

so geil :D

Das haben wir uns letzte Woche in Audiologie angesehen :D

so funny! :D

[turalb]

awesome! so funny:)

[dongjian0406]

saw it in lecture today! awesome!

[SpookyNooky]

Responsible for this "dance" is a motor protein called "prestin" in the membrane of the outer hair cells. It has voltage sensors, which trigger the length changes of this protein.

[Fil0403]

Throw some drum & bass.

[thenavneet9]

we saw this in class we're doing a test on that soon

[Nekosculta]

rofl

[JorikvanRijn]

Awesome! Saw it in today's lecture, had to fav orite this one ;)

[emacwakeup]

i thaught hair cells sway .. not dance!! haha!! this stuf 2 funny!! haha!!

[pierrelepoisson1]

my teacher showed us this vid!!! its hiarious!

[momomoose]

Haha my Physiology prof showed this to us yesterday :D

I had to come on to fav it XD

[supermanadamio]

same with me!

[momomoose]

lol Oh my, you're not in my BIOL361 class are you?? haha :3

[supermanadamio]

omg I could be... you know, me being in Australia and all. lol.

[momomoose]

haha Long-distance ed maybe ^^

[skeltim]

The Fuck...

[Nydracommander]

i think the cell is reacting to voltages send through the patch electrode, not to the music. It's probably just added later

[sugarplumapathy]

lol

[andreatrv]

Definitely an OUTER hair cell, they have the protein prestin which make them motile (they move) in response to voltage changes.

Saw this in a talk by Peter Dallos :)

[evicime]

this IS a hair cell, these cells are in the inner ear, and are the receptors of hearing. (In this movie, the hair cell is sitting on a patch pipette.)

[MrFilatova]

Yes, it is a hair cell from the inner ear, or more specifically an isolated outer hair cell from the Organ of Corti; but these cells are not responsible for hearing sound - they are responsible for amplifying it. The 'inner hair cells' on the other hand are responsible for transducing sound (pressure) waves into electrical pulses that reach the brain via the 8th cranial nerve and are interpreted as sound.

[werekorden]

@MrFilatova You missed something.  The Outer haircells are also responsable for sharpening the sound. So the are important for hearing. Because otherwise you wouldn`t hear a distinct tone you would hear a somehow broader sound.

[di62zani]

i think that is hear cell....not hair....i did see it in a congres...

[crunchyleavesaflow]

lol, thank you

[elli14981]

I want to show this in my class (i am a teacher). The kids will probably ask how this is videotaped. Does anyone know? On a human body?

[leungh10]

An isolated hair cell (don't know from what animal) was secured by a patch electrode in a petris dish with physiological solution. The shadow at the basee of the hair cell is the patch electrode. For detail on how a patch electrode is made, please google it.

[oOluvangelOo]

ummm what is the song?

[xpeperx]

rock around the clock of Bill Halley

[tuttuthupe]

I thought only the outer ear cells can "dance" because the internal ones have no "muscles" !!

[aldalote]

You're correct that it is the outer hair cells that have this response, but what I think they're referring to in the description it the fact that it is a cell from the inner ear (i.e. the cochlea).

[TheGameShogun]

so this is what we pay government scientists for???

[Cheyenne17124]

What happens when physiologists are in the lab too long.

[theunraveler]

lol...now all it needs is for the hair cell to play a banjo...that would be so cool

[theunraveler]

lol...now all it needs is for the hair cell to play a banjo...that would be so cool

[nbalaji87]

cool stuff ross...

[DaveShi]

Ross. This video has single-handedly rejuvenated my passion for learning.

[gymman1031]

Thanks for the video! My dad gets hairs in his ears and hates them. Therefore, he picks them out with tweezers. We tried to see if laser surgery could be performed on his ears so that he wouldn't have hairs in his ears anymore, but they said they couldn't do it. If a way is invented, I'm sure my dad would jump on it!

[eisenhauer89]

yeah, but here are different hairs mentioned.

These inner ear hairs are so tiny, that a loud sound could destroy them. If these hairs are deformed oder destroyed, it often causes tinnitus. Anyway best wishes for your dad ;-).

[aldalote]

Actually, this isn't even a hair, it is a single cell from the Organ of Corti inside the Cochlea that responds to sound waves. It is a part of the hearing mechanism.

[Fil0403]

@aldalote Actually, the title already clearly states it's a hair cell, not hair, so I don't see the reason for the clarification, but thanks anyway.

[aldalote]

@Fil0403 My comment was made way back at the beginning of the comments (a year ago) where, if you look, there are several people who didn't understand that there was a difference between and ear hair and a hair cell.

[DarkBabyIon]

@aldalote

They are CALLED.HAIR CELLS

[MrAzulay]

@aldalote Actually, this isn't even a cell, it is a single piece of cheese from France. It is something you eat.

[antk11]

that's so funny! and interesting! i just played it three times and couldn't stop giggling.
