Poster Presentation: no. 3092INTRODUCTION: In rats, cocaine alters dendritic morphology (1), a determinant of cortical thickness (CT). In humans, addiction vulnerability traits such as anxiety and impulsivity relate to CT (2, 3). In human cocaine users, CT differences have been noted (e.g.,(4)) but little has been done to elucidate network functioning related to these differences. Numerous studies have also noted resting state functional connectivity (rsFC) differences in cocaine users (5, 6); however, how these may relate to structural differences is unknown. We identify cortical thickness differences in cocaine users, then probe relationships to rsFC and use characteristics in order to ...postprin
