Nature vs. Nurture: The Neurobiology of Individuality

(4 Credits)

Psychologists, biologists, philosophers, and neuroscientists have historically questioned the impact of heredity vs. the environment in shaping the uniqueness of individuals. Modern scientists have arrived at a consensus whereby both genes and experience contribute to distinct behaviors. Indeed, “nature” and “nurture” are not isolated components. Understanding the constant and complex interaction between the two is the key to unlocking the mysteries of animal and human behaviors. We examine the nature vs. nurture debate over time by studying Darwin and Lamarck, as well as novel genetic tools that explore the interaction between DNA and the environment and papers treating the topic of genes and behavior. Group assignments will involve case studies that require students to gather evidence, propose solutions, or offer possible explanations for specific intrinsic vs. extrinsic situations. Students will also write research papers on topics and in a style accessible to the general public. Examples of paper topics include: inheriting trauma; the genetics of neurological disorders; the microbiome and your brain; and the science of addiction.
