When surveying public health at any, level there is an emphasis on prevention. If we can understand why people make specific health related decisions, we will be better equipped to circumvent, or ultimately prevent individuals and/or communities from engaging in potentially adverse health behaviors. In the realm of public health there is a discipline devoted entirely to understanding health behaviors among various populations and individuals. The specific area of research I am involved in with Dr. Susan Ames at SCGH focuses on increasing our understanding of automatic and cognitive control processes. This research evaluates the neural correlates of substance use behaviors by utilization of MRI scans to observe individual and group differences in specified brain regions that become active during substance-related implicit association tasks and during an inhibitory control task.
