UC, San Diego presents this free online course, exploring the secret workings of the human brain. In this series of audio lectures, Dr. Terry Jernigan guides students to a better understanding of the chemical and biological mechanisms behind our thoughts, memories, and emotions. After all, humankind may have mapped every corner of the earth and even some far off reaches of outer space, but the depths of the human mind remain largely uncharted. Why do we sleep and dream? How are memories stored? What is consciousness? These are just a few unanswered questions being explored in the exciting field of cognitive neuroscience.
