You know, it really is so incredibly complicated. It's breathtaking. Like, it's magnificent and it's a challenge. Like, I think there's no way it's all just one big thing.

Yeah, there's two that I'm particularly taken by.

Just the mind drifting, that sort of feeling, you know? If you're a bit bored, you know, probably after I go on for five minutes, everyone's brain will be in this state.

So every so often the individual is doing something and then the offline brain pops up and turns it off when it shouldn't do. So there's an imbalance between the offline and the online brain.

There are these fantastic information processing loops in the brain. They go deep in the brain and then they go to the surface of the brain, the cortex, and then they go back. And these information processing loops are what controls attention, cognition, everything.

And in ADHD, the thought is that they're a bit disrupted, that the flow of information sometimes goes a bit awry.

Gosh, just meet 100 people with ADHD. After meeting them, you're not going to think they've all got the same thing going on. It's just not like that.

It's a slight shift in how the brain functions or talks to itself or is connected.
