Brain networks are groups of brain regions that work together. There are only a handful of interesting ones, but you can actually use them to understand human behaviour.

Not brain regions, brain networks

Article

Brain regions are often oversimplified in popular discourse. The amygdala isn’t just the fear centre, and the prefrontal cortex isn’t solely the ‘smart’ bit. This silly approach to talking about the brain hides the really cool stuff. So let’s talk about those instead.

If you look closely, you’ll see that our ability to speak just hides the fact that other processes are running the show. Find a way to cut the language regions out, and you see other little consciousnesses start to take over.

Mini-brains inside the brain

Article

People love to talk about brain regions, but usually that’s silly. Brain regions usually don’t tell you anything about how the mind works. That’s not true of the language regions though. The language regions tell you something quite weird about the mind, and it has nothing to do with language.

Basically, reward and ancipation both use the same system, but differently. Anticipation seems to come in through the senses and get sent throughout the brain, but pleasure seems to come in from more evaluatey bits—maybe to help us learn what’s rewarding.

Anticipation beats reward

Article

A lot of people reckon the brain treats rewards quite differently from the anticipation of rewards. And, in fact, the anticipation of reward seems like the bigger driver of our behaviour. And this little tidbit is one of the few places where human behaviour is actually explained well by exploring the brain. So let’s explore it.

The neural reward circuit implies that small, rewarding tasks that share environmental context are going to be the most addictive, so break tasks into small steps that end in a clear good feeling and optimise for a shared environment.

Addictive Work

Article

It’s very trendy to say stuff like ‘start your day by making your bed and something something life is better’. But this is usually some kind of comment about the value of small and simple acts in promoting a sense of order and discipline. I’m not so interested in that. I’m more interested in those small and simple acts that make you addicted to those acts. I like other things that people say are addictive, so this sounds much more my speed, when it comes to productivity.

The brain is an <em>integrator</em>. It takes in information from all over the body, and puts it together to decide how you should act. This messy integration acts as a bottleneck, forcing the brain to streamline as much as possible. Rarely does it try to ‘think’.

Brain structures and behaviour

Article

A lot of people like to talk about the role of various brain regions in human behaviour. Fewer like to talk about brain structures. But in many ways, looking at the brain structures rather than all the different subdivisions into regions tells a cleaner story about behaviour. Let me show you how.
