The “triune brain”
This myth is the idea that the human brain evolved in three layers.
- The deepest layer is known as the lizard brain and said to house our instincts.
- The middle layer - the limbic system - allegedly contains emotions inherited from ancient mammals.

Modern research has revealed that the brain doesn't evolve in layers but is built from a manufacturing plan using the same neurons.
