The reptilian brain contains the cerebellum and brain stem. It is present in reptiles and therefore called the reptilian brain. It is the oldest part of the brain and regulates vital functions like breathing, heart rate and flight or fight response.
No, the amygdala is not the entire human reptilian brain. However, the amygdala is a part of the brain's limbic system and plays a role in processing emotions, particularly fear and aggression. The reptilian brain refers to the brainstem and cerebellum, which are involved in basic survival functions.
The 3 main parts of your brain are your neo-cortex, Limbic and the reptilian brain. The neo-cortex is your big learning engine, your limbic brain controls your emotions and the reptilian brain controls what you do and so on.
The term "reptilian brain" refers to the most primitive part of the brain, known as the brainstem and basal ganglia, which is responsible for basic survival functions such as aggression, dominance, territoriality, and basic emotional responses. This concept, popularized by neuroscientist Paul MacLean in his triune brain model, suggests that these structures are similar to those found in reptiles, emphasizing instinctual behaviors vital for survival. While the model has been criticized and is oversimplified, it highlights the evolutionary aspects of brain function.
Brainstem
The reticular formation is a network of neurons located in the brainstem. It is involved in regulating arousal, attention, and sleep-wake cycles.
No, the brainstem is down low, like the stem of a flower.
