How To Operate Your Mind: The Eight Circuit Model of Human Psychology By: Timothy Lee Alley Also known as the Eightfold Model of Human Intelligence, Dr. Timothy Leary suggested that our brains are made up of eight mini-brains or circuits. Each of these eight circuits are designed to allow us to automatically adapt to different aspects of reality. Development of specific circuits more than others are found to be determining factors in our behavior and our decision making. Detailed study and understanding of the brain now allows us to focus our attention on specific activities and stimuli to guide our consciousness, and possibly others, through this eight circuit maze to find peace and happiness.
