What is a cortex? - From the Latin word for tree bark, “cortex” refers to the outer most layer of an organ. In the brain, the outer most layer is made of several layers of neurons. That’s true in the cerebellum,

What’s this “cerebellum” thing for? - It’s sitting underneath your cerebrum, this odd bulge behind the brainstem. Only ten percent of your brains total volume, it has more than 75 percent of the neurons. What is the cerebellum,

Reverse engineering the brain… ish - Let’s see… How does this “brain” thing work exactly? Maybe we could build something brain-like, something that would act as though it has a mind. Hmmm… In a conversation that rambles through blind cavefish,

A network of networks - It’s an old part of your brain, but still very complicated. With far too much to cover in one episode, Phil and I hit a few highlights of your reticular formation. From our old friend the substantia nigra; to the raphe nuclei a...

The gas and brakes in your brain - Philosophy was fun, but let’s get back to looking at the brain, and the bits there in. Today we talk about a system that helps to activate and control the way you move. It’s one part of what’s happening in your “basa...

Brains and batteries, oh my - Our last recording went a little long. We split it in two, and this is the second part. Today we talk about the somewhat gruesome history of studying the electrical activity of the brain.

Bloody brains! - The parts of your brain that are working the hardest, need the most blood. Your brain actually pulsates with your heartbeat, and the flow of your blood within your brain changes from minute to minute.
