Methods used to examine the influence of cage shape/size on social interactions in mice.

<p>(A) Setting used to track with Mice Profiler the <i>occupant</i> male (red) and the <i>new-comer</i> male (green) during social interactions in a rectangle, a round and a square cage. (B) Behavioral events detected by Mice Profiler during social interactions between the <i>occupant</i> (red) and the <i>new-comer</i> (green). (C) Spatial occupation of the interaction cage by the <i>occupant</i> (red) and the <i>new-comer</i> (green) for the eight pairs of mice in the three cage types. Yellow traces represent the overlap of the two spatial occupations.
