THE BRAIN: STRUCTURE, FUNCTION AND EVOLUTION
Weekly Overview and Expectations
Course DescriptionThe human brain is an enormously complex system. It regulates all of our physical and mental functions and shapes who we are. This six-week course explores this remarkable organ: how it has evolved, how it works and how it changes over the course of our lives. Each week, participants will draw from essays, media resources, textbook readings and online discussion forums to explore aspects of brain function - from sensing to decision-making to expressing ourselves. A weekly case study, written by a specialized neuroscientist, will describe cutting-edge research in areas as wide-ranging as using functional MRIs as a diagnostic tool, the neurobiology of hearing and the evolution of mammalian brains. Students will complete the course with a solid grasp of how the brain works, how we know what we know and the exciting research prospects ahead. Student Learning OutcomesIn this course, students will:

Weekly Overview and ExpectationsWeek 1: How Does the Brain Work? We begin with the nervous system, exploring the basic anatomy of nerve cells and the breathtaking speed and complexity with which they communicate. Then we take a tour of the main components of the brain and their primary functions. In the case study, neuroscientist Dr. Joy Hirsch describes looking inside the living brain with functional MRI, what we can (and can’t) learn in the process, and how it can be used to diagnose and treat disease. Expectations
Week 2: How Do We Sense? How do our brains transform a barrage of sensory input into what we experience as vision, smell, taste, hearing, and touch? The week starts with the sense organs themselves, which are remarkably different from one another, and goes on to examine how and where in the brain the information gets processed. The case study by neuroscientist and surgeon Dr. Dylan Chan is an in-depth look at the mechanisms of hearing and deafness. Expectations
Week 3: How Do We Feel? Looking beyond the concepts of short- and long-term memory, scientists have discovered that different kinds of memory involve different parts of the brain, and also play a part in how we express emotions. The anatomy of emotions is complex as well, involving the limbic system along with complex connections to the rest of the brain. The case study, by Dr. Gabriel Corfas, explains what can be learned about social interactions and learning by studying model organisms. Expectations
Week 4: How Do We Think? From imaging studies, scientists have learned that most people have a primary language area on the left side of the brain that processes the literal meaning of words. Split brain studies, however, tell us that both sides of the brain need to communicate in order to correctly interpret complex sensory stimuli like language and integrate words with our emotions and memories.. This week we discuss these and other processes unique to the human brain: planning, problem solving, and decision-making. The topic of this week’s case study by Dr. Paul Glimcher is "neuroeconomics": an interdisciplinary approach to understanding the neural events that underlie behavioral decision-making. An interactive explores the structures and neurotransmitters involved in different emotions and how that influences our decision-making. Expectations
Week 5: How Do Our Brains Change? While the number of neurons in our brains is essentially fixed at birth, the number of connections between them grows over the course of our lives. This means that our brains are profoundly affected by our experiences, and also that we have the ability to recover from trauma. Late in life, certain brain cells start to deteriorate, although physical and mental activities can help compensate. Dr. Michael Merzenich explains how appropriate training can drive plasticity processes to help people recover normal function. Expectations
Week 6: How Has The Brain Evolved? In the final week we’ll start with a tour of the nervous system through the tree of life, and then focus on one extraordinary human attribute: the capacity for abstract thought. Anthropologist Dr. Ian Tattersall discusses how at some point in our evolutionary past, humans developed the ability to use symbols to represent our interior and exterior experiences. We’ll look at the evidence for when these capacities arose, and paleontologist Dr. John Flynn will take us back into the early mammalian record to explain how brain size evolved. Expectations
