Our #limbic system, which Dr. Dorn calls the “old brain” that we share with the most primitive animals, is emotional and instinctive. It comprises various structures such as our amygdala, and it’s highly interconnected with the nucleus accumbens, brain’s “pleasure center.” According to Dr. Dorn, it constantly tells us “Yes, yes, yes! Eat more, drink more, have more sex, take lots of risk go for all the gusto you can get, and above all do not think!”. On the other hand, the “new brain” called the #neocortex, a part of our cerebral cortex, that is responsible for thinking, planning, language, and decision-making, some of the very faculties that makes us humans. It’s job, as Dr. Dorn puts, is to tell us “No, no, no! Don’t do that because it’s dangerous, makes no sense, and is not in your best interests, or those of your family, or of society.”
