The human brain, a remarkable organ with close to 100 billion neurons and trillions of connections, developed through evolution for survival and procreation, not for accuracy. As amazing as its capacities may be, it is equally amazing what our conscious minds cannot do, what we miss, and what we sense that is not there. Why are there optical illusions? Why do we believe obvious lies? How are men's and women's or conservatives' and liberals' brains different? Advertisers and politicians use this knowledge to take advantage of us. Designed for the lay person, this course does not require a science background and will include presentations, discussions, videos, and demonstrations. We will discuss how to overcome some of the brain's limitations and how to keep it active and healthy. We will look at how our brain has evolved and how it is likely to evolve further.

Despite its 100 billion neurons and hundreds of trillions of connections, our brain developed for survival and procreation, not reason and accuracy. Advertisers, trial lawyers, and politicians find us easy to fool. We will study how the brain works and examine differences in brain structure between men and women, between conservatives and liberals. We will learn about the 'reptile brain" and how little we have evolved from that state. We will look at why our brain works as it does, how it lets us down, and how we can extend and improve our use of it. We will also look at the brain's evolution through the centuries, and how it is likely to evolve further. The course includes demonstrations, discussions, videos, and experiments; no science background is required. Lecture (plus questions). Facilitated Discussion. Viewing Videos.
