Franssen1, Massimo Bardi2, Kelly G. Lambert1 1Department of Psychology, Randolph-Macon College, 2Department of Psychology, Marshall University The comparative species approach allows behavioral neuroscientists to explore various neurobiological factors associated with specific behaviors viewed as characteristic of a specific animal model.
