SLC6A3 and Anxiety: DAT GLS1 cHET mice do not show several behavioral phenotypes of DAT VGLUT2 cKOs, such as decreased novelty-induced locomotion, motor deficits on the rotarod, an anxiety phenotype, or blunted responses to psychostimulants (Birgner et al., 2010; Hnasko et al., 2010; Fortin et al., 2012).
