Stanford University.

--out by now, I am not Dr. Sapolsky.

You probably got some cues from the beard and other things.

My name is Nathan.

I'm a graduate student.

I'm a fourth year PhD student in the neuroscience program.

And I'm going to be giving you the introductory lecture today

on, basically how the brain works.

And just to get a sense of who is here before I get

started, how many of you are either

a biology major or HumBio majors and decided to come today?

That's a lot of people.

OK.

How many in other hard sciences or engineering?

A few.

OK.

How many in the social sciences?

A few.

And humanities?

All right, humanities.

Anybody else in anything other?

OK.

We've got a few others as well.

OK, great.

So for some of you, this is going to be a review.

And hopefully, you'll still learn something new.

For some of you, this is going to be the first time

that you're hearing these terms.

And hopefully, this will give you

just a very general background so

that when you hear Dr. Sapolsky give lectures

on neuroscience later, you have a better understanding of what

he's talking about.

So we started out this whole course talking

about the everlasting question of,

why did the chicken cross the road?

Yes, that's supposed to be a chicken.

My major is not art.
