And so we have a different target to go after for treatments.

What can we do to sort of boost, you know, a hub that's been damaged as opposed to thinking about it in a...

in a less specific way.

And then also, as we really start to learn about how the brain is organized in these networks, we've also learned that measuring your network structure is very predictive of your well-being and how you respond to interventions.

So there's a metric called modularity.

which measures how organized your brain networks are.

And the brain is made up of different modules, different networks.

And these networks can either be very communicating with each other or not so communicating with each other.

And the more segregated they are, we call that more modularity.

They're kind of separate entities.

They're modular.

And it turns out we can measure that with fMRI.

We can put someone in the scanner.

We can do this resting thing.

fMRI scanning and then we can measure how modular your brain is versus my brain and all of us are very

different levels of modularity.

Yeah, it turns out that it seems to be more advantageous to have more.

So we can predict... More separateness of brain function between areas.

Yeah, that the networks are sort of more independent.

That doesn't mean they don't talk to each other, but at sort of baseline, they're more independent.
