Fig. 1

(A) A side-view of the three-chambered box used for sociability testing. For automated scoring, the box sits on a blue mat that covers a transparent Plexiglas stand. Below are 11 Infrared (LED) Lighting Kits that illuminate the floor of the box. In front of the box are two 0.5-kg weights that are placed on top of the cylinders, and the paper weight that serves as a novel object. (B) A screenshot from TopScan (Clever Sys., Inc.) software. The upper portion shows the video image, in which an albino (BALB/cJ) mouse sniffs the left cylinder and is silhouetted against the infrared-lit floor. The lower portion shows the software’s location of the mouse, both cylinders, and each chamber. (C) A close-up of the mouse sniffing the cylinder. The yellow circle outline in the top panel shows where the software operator has drawn the cylinder’s outline. The yellow circle in the bottom panel indicates the cylinder’s location, including a 4-mm extension of the radius.
