Did you know the resting brain uses more energy every day than 30 minutes of strenuous exercise does? 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.
