Let’s explore the most complex computer system on Earth: the brain. On this episode, we’ll examine this wondrous organ — what we’re learning about it, how it works, and what we can do when things go wrong. We’ll look back at the dark reputation of one of the most controversial mental health treatments, electroconvulsion therapy, dig deep into the brain to pull out blood clots of stroke victims, and even look up to the sky to try to understand how groups of animals can move as if they have one brain.

Putting your thinking caps on.
