We want to know how the brain understands the world. When we look at things, we 
know what to do with them. We can imagine picking them up, throwing them 
around, what they feel like, what they sound like. We do not know how to give 
this power to things made by man.

We try to understand this power by looking into the animal brain while it plays 
around in interesting worlds. When things in the world change, animals are 
surprised and look like they are trying to explain what happened. After that, 
they move in a different way when they expect the world may change. By looking 
into their brains before and after the animals change what they expect, we hope 
to learn more about the brain’s power to understand worlds.

When we try to look into the brain, we are faced with a big problem. The brain 
is made of many cells that work together. We can hear them working, but we can 
only listen to very few of them at a time. Because of this, we try to build 
better ways to listen to more cells so we can understand what they are 
working on.
