Sexually Dimorphic Regulation of Behavioral States by Dopamine in .

Sex differences in behavior allow animals to effectively mate and reproduce. However, the mechanism by which biological sex regulates behavioral states, which underlie the regulation of sex-shared behaviors, such as locomotion, is largely unknown. In this study, we studied sex differences in the behavioral states of and found that males spend less time in a low locomotor activity state than hermaphrodites and that dopamine generates this sex difference.
