Dr. William Overman, Professor
My current research interests concern the roles of the prefrontal cortex as they apply to decision-making, olfaction, and development. My students and I are investigating how decision-making performance may be changed by having participants smell various aromas and/or deliberate various cognitive dilemmas, both of which engage different regions of the prefrontal cortex. This work has implications for "risky" decisions made by adolescents in whom the frontal lobes are undergoing significant neuroanatomical and chemical changes as they mature into adulthood.
