FIGURE 1.

A Schematic illustration of the IntelliCage system (A) with a close-up view of one operant conditioning corner (B). The IntelliCage system uses RFID transponders and computerized regulated access to operant conditioning corners for a group of up to 16 mice where individual behavior is assessed. A simplified version of the PhenoTyper and its use for the spot-light test of anxiety (C,D) and a possible addition of an operant learning wall (E). Unlike the IntelliCage and the Actual-HCA systems, behavior in the PhenoTyper is usually conducted in individually housed rodents. The Actual-HCA system uses a combination of visual monitoring with an infra-red camera and a RFID transponder system to monitor the positions of multiple mice in a standard housing cage (F,G).
