MAO-A^Neo mice showed perseverative responses. (a) MAO-A^Neo mice engaged in higher marble-burying activity than WT mice. (b) Both MAO mutants showed an increased digging behavior compared with WT controls. (c) In the water mist-induced grooming task, water mist elicited more frequent grooming bouts in MAO-A^Neo mice than their WT and MAO-A KO counterparts. (d) MAO-A^Neo mice also spent more time grooming than WT but not MAO-A KO mice. The values are represented as the mean±SEM. ^*P<0.05, ^**P<0.01, and ^***P<0.001 compared with WT mice, and ^#P<0.05 compared with MAO-A^Neo mice.
