Consistent with the observations in Nestin-Cre Utx cKO mice, these Emx1-Cre Utx cKO mice also displayed anxiety-like behaviors as indicated by decreased entry into the center zone in the open field test (Figures 2B–D), decreased entries (Figures 2E,F), and time spent (Figure 2G) in the light box in the light-dark box test. This evidence concerns the gene EMX1 and Anxiety.
