The three parts to our brains
1. The reptilian brain (basal ganglia and brainstem) handles basic drives like hunger as well as habits and procedural memory (like putting your keys in the same place every day without thinking about it or riding a bike).
2. The paleomammalian brain (hypothalamus, hippocampus, amygdala, and cingulate cortex) is the center of our motivation, emotions, and memory including sight, smell, and sounds connected to memories.
3. The neomammalian brain (neocortex) enables language, abstraction, reasoning, and planning.
