Insecure... neurotic, and emotional.

Now this is the neurological goldmine, if you like, because a known reward excites people, but what really gets them going is the uncertain reward, the reward pitched at the right level of uncertainty, that they didn't quite know whether they were going to get it or not.

Excitement.

Freaked out.

I work with some of the most amazing people.

I do get carried away sometimes.

And, of course, neuroscience,

Are you excited?

How are you feeling?

Make you hot, Jason?

For who?

You know it's exciting.

Tal vez no sea del todo sorprendente descubrir que el cerebro de alguien que está enamorado se ve muy similar a uno bajo el efecto de la cocaína.

I should be in that video. ...lay me down

And it's in fact working.

Don't get excited.

Don't get excited.

I'm so excited. Yea.

It's not going to happen, not here, not like this.

You're not getting excited...

What, just for kicks?

Well didn't they tell you, don't you know?

You don't get your kicks outta this, do you?

So he does it again. Now, he gets excited.

I said.

Now, now, don't get excited. I'll tell you what to do.

The crowd goes wild.

Maybe he's excited that...

All right, just relax, will you?

AmAm I getting warm, here?

Hon, is the heat on? No?

I am so excited.

I could feel he was excited through his pants.

Oh Dre, I am so excited!

I am on fire!

I was excited by the movie.

You were getting excited?

Those yells? That unrest?

His body shivered with excitement.

My body shivered with excitement.

This culture knows that, this room knows that. It's exciting.

It makes me sick when I lose my temper.

He might be a bit scared.

He was very excited.

He was somewhat excited.
