Michael Dickinson How a fly flies

Here's a fly and a large infrared view of the fly in the flight simulator, and this is a game the flies love to play.

They fly in and they pollinate.

They're like tiny little flies and they fly around.

Stay on guard here. See that no one enters or leaves.

So for the first time we've actually been able to record from neurons in the fly's brain while the fly is performing sophisticated behaviors such as flight.

the curtains rustling, or a moth or fly beating against the windowpane.

The green trace at the bottom is the membrane potential of a neuron in the fly's brain, and you'll see the fly start to fly, and the fly is actually controlling the rotation of that visual pattern itself by its own wing motion, and you can see this visual interneuron respond to the pattern of wing motion as the fly flies.

You can let the fly play a little video game by letting it fly around in a visual display.

An insect's ability to fly is perhaps one of the greatest feats of evolution. Michael Dickinson looks at how a common housefly takes flight with such delicate wings, thanks to a clever flapping motion and flight muscles that are both powerful and nimble. But the secret ingredient the incredible fly brain.

Well, for many years in my laboratory and other laboratories around the world, we've been studying fly behaviors in little flight simulators.

during which the room was filled with the sound of a moth... or the buzz of a fly beating against the windowpane, which you only remembered afterwards.

Are you spider or fly?

Yes. She never hurt a fly, Clint.

There was a fly.

And he could shoot it from two rooms away and not damage what it was on because he knew how to pump it just enough to kill the fly and not damage what it landed on.

So this is the preparation that one of my former post docs, Gaby Maimon, who's now at Rockefeller, developed, and it's basically a flight simulator but under conditions where you actually can stick an electrode in the brain of the fly and record from a genetically identified neuron in the fly's brain.

And one of the lessons we've been learning is that the physiology of cells that we've been studying for many years in quiescent flies is not the same as the physiology of those cells when the flies actually engage in active behaviors like flying and walking and so forth.

And that is the case in flies.

So flies love this.

In the ointment you're the fly

Not a fly.

There's a fly in the noodle broth.

Mosquito and fly, they are big

She's prepared to clean teeth, but when she gets there, she finds out that there are no doctors, no dentists, and the clinic is just a hut full of flies.

A small mutation can take a two wing fly and make it a four wing fly.

They are dead fly larvae. You can wash them off with brine!

But I would argue that flies do more.

They're out there, thicker than flies.

And swat us away like flies, the way we swat away flies when we go into the rainforest and start logging it.

That's ridiculous, she wouldn't kill a fl

I'm not even gonna swat that fly.

We should fight against tigers (high ranking corrupt officials) immediately after we find evidence, and we should also deal with those flies (low ranking corrupt officials) at the same time. We should spread the principle of comprehensively strengthening party discipline to grass roots party organizations and make every effort to deal with those corruption problems in daily life of the general public.

The engine of the fly is absolutely fascinating.

They're a great model for flies.

This fly has a mighty sting, friend.

The whole bottle would not have killed a fly.

Even flies refuse to stand on his skin.

Now, how does this compare to a fly?

I saw a fly on the ceiling.

Of poor little me? I wouldn't hurt a fly.

I humbly thank you, sir.

There'll be Injuns around that herd thicker than flies.

Boy, when you flick a fly, you really

They trained the escape reflex that makes the fly jump into the air and fly away whenever you move your hand in position.
