Marked abnormalities in marble burying, digging and nest building are present in creatine transporter mutated mice. Marble burying (solid bracket) in (A) number of marbles buried, (B) latency to first episode of digging, and (C) total time digging. Creation of a nest was scored and is depicted in (D). Data is presented as mean + standard deviation. P values of ≤ 0.05 are shown with one (*) asterisk, ≤ 0.01 are shown with two (**), between 0.0001 and 0.001 are shown with three (***), and P values less than 0.0001 are shown with four (****).
