Dr Karl

Before you can say B, you have to say A. So you've done the first thing.

So get a thermometer and then ring back in if you had a thermometer.

And if you could give us some numbers and send us a picture of the numbers that you'd written down, you would be winning a Triple J fun pack right now, Dr. Furneaux.

But I think it's because you're accidentally activating the sympathetic nervous system to get you ready for threat.

So you're reducing the blood supply to your gut but increasing the blood supply to your muscles so you can run away and inadvertently getting a bit of a sweat.

Get the thermometer and you can get a Triple J Fun Pack, man.

Thanks, Dr. Furno.

Ah, when you're studying medicine, you basically just load your brain up with anything and you turn around to a junior medical doctor and you say, what are the 27 causes of clubbing?

And out it comes.

They open their mouth and out it comes.

And so it's been estimated that...

If you're trying to store information in a brain, like you do on a computer, you're looking at about 2,000 or 3,000 terabytes.

So a big hard drive on a computer would be 8 terabytes, normally 4 or 1 or half.

But that's only when you have digital static data.

But the brain doesn't store that.

It encodes the information through patterns of connections of nerves.

So in a computer...

maybe one transistor will talk to two or three others.

But in your brain, one nerve will talk to or be talked to by 10,000 other nerves.

And then also you've got the rates at which it fires and also it's continually rewiring itself.
