Let’s think about the brain as being built from the bottom up. Imagine you're on an elevator going up in floors. Each floor has corridors and rooms on its own, yet they all make up for the entire building. In the same way our brain is built in levels. In this episode we will start by looking at the most primitive part, the one that’s already online when we’re born, the so called Reptilian Brain. Right above the Reptilian Brain we have the Limbic System, also known as the Mammalian Brain. We can call this The Emotional Brain. In this episode we dig in a little deeper, starting to explore what happens inside our brain when we detect a threat or feel pleasure.
