Your reptilian brain, explained | Robert Sapolsky | Big Think

More about this content:

This content is about how the brain is composed of three functional layers: the reptilian brain, the limbic system, and the cortex. The reptilian brain is responsible for regulatory functions like body temperature and blood glucose levels. The limbic system is responsible for emotions, fear, arousal, and anxiety. The cortex is responsible for impulse control, long-term planning, and emotional regulation. It also discusses how the layers interact with each other and how conscious active thinking can be used to regulate more autonomic parts of the brain."
