Crocodile brain
Sources:
The concept of the "crocodile brain" often refers to the instinctive, reactive part of the human brain, primarily the brain stem or what's sometimes called the reptilian brain.
explains that this part of the brain is focused on survival, reacting quickly to threats, similar to how a crocodile might respond to danger. It's responsible for basic functions like heart rate, breathing, and fight-or-flight responses. In relationships, if both partners are constantly in this reactive "crocodile brain" state, it can lead to conflicts and anxiety, impacting overall mental health and sleep quality 1.
further clarifies that the reptilian brain includes the brain stem, which is preoccupied with essential survival functions. This brain segment ensures we react quickly to threats to stay alive, much like reptiles 2.
For a more in-depth understanding, it's helpful to consider this information in the context of integrated brain functions involving both the reptilian brain and higher cognitive processes in the neocortex, often symbolized as a "wise owl" brain 1.
