Loretta is the author of Habits of a Happy Brain: Retrain Your Brain to Boost Your Serotonin, Dopamine, Oxytocin and Endorphin Levels. She's Founder of the Inner Mammal Institute and Professor Emerita of Management at California State University, East Bay. Dr. Breuning's many books, videos and podcasts explain the brain chemistry we've inherited from earlier mammals. She shows that our "happy chemicals" are not designed to be on all the time. They evolved to do specific jobs, so we always have to do more to get more. Dr. Breuning's work explains the natural way to enhance our power over these chemicals. Her nine books have been translated into sixteen languages. Before teaching, Loretta worked for the United Nations in Africa. Today, she gives zoo tours on animals behavior, after serving as a Docent at the Oakland Zoo. She is a graduate of Cornell University and Tufts. The Inner Mammal Institute offers videos, podcasts, books, blogs, multimedia, a training program, and a free five-day happy-chemical jumpstart. Details are available at InnerMammalInstitute.org.
