There's no brain activity.

It's neural activity, brain scans.

That's a gorgeous brain. Nice activity.

Brain activity's all over the place.

Let's give an example of where we think this is going to go.

The end is nearing, it's nearing.

Okay, so what?

There's a lot more arrows.

Your own brain function is interfering with the process.

Your brain's still active, but you don't remember a thing.

Our brains control our activities.

Increased respiration rate, Blood pressure, brain activity.

Their groundbreaking technology records the EEG, or the electrical activity of the brain, in real time, allowing us to watch the brain as it performs various functions and then detect even the slightest abnormality in any of these functions vision, attention, language, audition.

We are always chasing storms.

You see all these points of light behind you.

All this activity is simply the result of doing nothing.

learned that they could track blood flow to map non invasively where activity was going on in the human brain.

And I said, I don't know.

They're also very obsessed with status.

Thank you.

In fact, the so what is, in the brain, changes in neural activity, the things that make your brain work, the things that make your software work in your brain, are tightly correlated with changes in blood flow.

Okay. Get ready.

The patient then stays in the hospital for a few days, waiting to have a seizure with the electrodes constantly recording the activity inside his or her brain.

A single second, stretched into a thousands steps shows swells of activity sweeping all over my head.

What it's all about is the selective representations of things that are important to the brain.

Actually, the first time we recorded more than one neuron a hundred brain cells simultaneously we could measure the electrical sparks of a hundred cells in the same animal, this is the first image we got, the first 10 seconds of this recording.

Action

This is actually a brainwave sensor that's reading the electrical activity of my brain as I give this talk.

Imagine that this is what your grandmother looked like, the activity that your grandmother evokes in your visual cortex, during your interaction with her.

We're probably not going to make a deal here.

Percentage of activity

So what you see here is a subtraction of areas in which there's more brain activity when you're playing people compared to playing the computer.

A lot of brain activity.

The resistance is growing.

When they do brain scans

As when a human is intoxicated?

So we could look at the same brain when it was in that heightened state and when it was in a resting state.

System Activity

I'm spying.

Start a resistance?

Without needles and radioactivity, without any kind of clinical reason, we can go down the street and record from your friends' and neighbors' brains while they do a variety of cognitive tasks, and we use a method called functional magnetic resonance imaging.

That we're gonna kickstart his brain.

Active, inactive.

PTSD involves changes in the brain.

Were they playing more notes when they were improvising?
