Normal social approach behaviors in <i>Auts2</i>-deficient mice.

<p>(A) Sociability for contacting an unfamiliar mouse or empty chamber (middle graphs) and social novelty for a stranger mouse versus a familiar mouse (right graphs) of WT and <i>Auts2</i> mutant mice were measured by a three-chamber test. Graphs show the time spent in the each chamber. Data are presented as the mean ± SEM (WT, n = 16, <i>Auts2</i>^<i>neo/+</i> = 13), t test.
