They recorded from these neurons and they found these neurons that at first were quite difficultly believing that they exist.

So they showed people.

So in a mouse lab or in a monkey lab, we would have shown random dots or something.

Banana.

But, you know, human, particularly in this part of the brain, hippocampus, amygdala, like the entorhinal cortex, don't much care about that.

So we showed them things that people care about, buildings, famous buildings, people, actors.

And then we found there was a Bill Clinton cell and there was famously a Jennifer Aniston cell.

And then – so there's a cell –

So you only have a limited amount of time.

It's important to know.

So we cannot show them all possible images of all possible actors.

It's simply not possible.

You show them 100 or 200 images.

Each image you want to show three or four times, randomly shuffled.

So it turned out there were some cells that responded uniquely to specific individuals, like Jennifer Aniston.

Not interestingly, she was married at the time to...

Brad Pitt.

Thank you.

So the neuron didn't fire to Brad Pitt and Jennifer Anson, but fired specifically to different pictures of Jennifer Anson.

Some other cells fired to other people, including sometimes their name.
