Assessment of Dbh −/− and Dbh +/− mice in the elevated zero maze. Dbh −/− mice did not differ from controls on anxiety-like measures, including a % time in the open (anxiogenic) segment and b entries into the open segment. There was a significant genotype difference in c average velocity and a trend for d total distance traveled. N = 9-10 per group, *p < 0.05.
