“Humans have three brains speaking different languages: physical/reptilian brain speaks through actions and physical things, emotional/mammalian brain communicates through feelings and relationships, conceptual brain uses symbols and abstract ideas”
About Dr. Paul MacLean
American neuroscientist who proposed the triune brain model — describing the human brain as three evolutionary layers (reptilian, limbic, neocortex) that govern instinct, emotion, and reason. Frequently referenced in marketing and persuasion frameworks that map messages to brain layers.

Triune Brain Model and the Unconscious Battle Behind Every Purchase
According to Dr. Paul MacLean's triune brain model, humans have three brains: reptilian (survival), mammalian (emotions), and neocortex (logic). These brains constantly fight for control and operate with different currencies, making decision-making an unconscious battle between competing motivations.
