It's got a good beat and you can dance to it

Very cool Danio! I am looking forward to your neurobiology series.

Nice that they picked a fat one in the frequency range I can still hear. Apparently I have a watch with an alarm that goes off at 2:15 every afternoon. Never heard it.

I'm studying sensory neurobiology at the moment, and I thought it was just the tip (that looks a bit like a stanley knife towards the top of the frame) that responded to the movement of the tectorial membrance?

Cool video though ;-)

Ah, wait, I worked this out - was it the protective reflex protecting the cell from damage?

David,
The movie is of an outer hair cell from a mammalian cochlea. OHCs exhibit electromotility as part of their normal function.

Not that it's surprising to see cells responding "exactly" to what they're sensing, it's very cool to see it happen.

Does this mean that our auditory cells are possessed by 50s rock sounds?

OHCs were discovered by Jonathan Ashmore at the UCL Ear Institute, and are thought to be involved in amplification.

Ashmore also made this film clip. He gave a lecture on the cochlea last year, which I attended as part of my M.Sc. programme. He showed us the clip, and told us that he added the soundtrack when his work was featured in a BBC documentary.

You wouldn't rickroll us, would you?

You know what? I like Pharyngula all the time but I also think PZ should go away more often. He does such a good job choosing his guest bloggers.

I am looking forward to that, Danio.

I already did the ScienceBlogs survey. I'm still waiting for my free MacBook. ;)

Nice, but it won't make the cut for So You Think You Can Dance.

Where are these low frequencies you speak of. In 1955 they could barely record the mid-ranges. Play the little thing some Dr. Dre or Prodigy or DJ Aphrodite... heheh

Sure, impressive and everything but can it TANGO!

Obviously the mechanosensory hair cell was Designed to like Heathen Music! Onoez teh debil designed it!

Cool video though.

I find it surprising that the survey was so obviously targeted towards Americans. Or perhaps not, but then they should have made it clear from the start that the rest of us should fill it out.

I am surprised that the survey was so obviously directed toward Seeds advertising interests. How much TV? How much travel? How many personal services?

Why not, How many books do you read each year? Discouraging, but I guess they gotta make a buck.

So those are the same hair cells from the organ of corti in the ear? Suhweeet.

The movie is of an outer hair cell

So its true; my hair got legs. Who'da thunk it?

[Referring to other comments here, seeing such basic behavior makes dance shows a little less impressive. But just a little.]

I don't know why but I watched it and it made me giggle. Is it supposed to do that? And thanks for the warning on the sound but luckily I wear headphones all day long where I work so no worries for me hehe.

That's pretty cool. But, is this real? I'm assuming it is, but I know I could fake this sort of thing in AfterEffects if I wanted to.

Copy editor!!
The cells (that's the C in OHCs) were "discovered" well over 100 years ago...dude named Corti?

It's the electromotility that's news. I remember when I was a TA for Comparative Physiology back in the late 80s, the prof that semester, Peter Narins, had just returned from a conference where he had heard for the first time the news that OHCs were effectors, not sensors (I gather that now they are thought to be both?) ...a clearer demonstration of the (occasional) thrill of science you could not ask for; the guy was beside himself with intellectual excitement.

Boo - missed the survey again. I can't keep up with you people.

Oddly adorable cell, really.
