The Triune Brain Reptilian brain body regulating, unconscious Old mammalian brain limbic system plus reptilian brain Neo-mammalian cortex, plus the limbic system, plus the reptilian brain Each layer elaborates the more primitive layer. e.g., the reptilian brain in humans is more flexible in humans because it has access to the limbic system
