Nicky Case made an interactive explanation of how neurons work. It’s part narrated video and part game.
But the most important concept I wanted to introduce here was exposure therapy, which is part of Cognitive Behavioral Therapy. CBT is basically being mindful of your crappy neural connections, and gaining skills to retrain those connections.
I like how Case’s narrated responses change depending on what and how you click. It feels like he’s sitting there next to you.
You’ll want to set aside a bit of time to click through. It’s on the long-ish side by internet standards, and there’s no way to pick up where you left off if you come back to it later. Or, you can download the open source code and do it yourself.
