Reward & Addiction
Spatial Place Preference Box
The apparatus consists of a box with two equally sized compartments interconnected by a rectangular corridor. The compartments are differentiated by the motifs painted on the walls (dots or stripes) and the color (different shade of grey tones, light or dark) and texture (smooth or rough) of the floor. The innovation of our box is the possibility to combine a new additional spatial dimension allowing the animal to differentiate the different compartments in a more discriminative manner. Transparent walls are also used to minimize the time the animal spends in the corridor. The introduction of these new discriminative elements allow: • Optimizing the results obtained in the place preference and aversion paradigms (low variability in the response, reduced number of animals per group)
key features
Reward & Addiction • Spatial Place Preference Box
} Allows combination between the visual, tactile and
spatial cues defining each compartment
• Organizing the discriminative elements in a wide variety of configurations for studies evaluating spatial or contextual memory • Using the elements as discriminative cues associated with drug exposure in other diverse experimental designs. The spatial place preference box can be used with SMART or LimeLight video-tracking systems for detection and analysis of animal position throughout the test, see page 4 or 10. It can also be used with PPCWIN, see page 84.

Our spatial place preference box is an experimental chamber developed to optimize place preference and aversion studies in small laboratory animals, especially mice. The design of the box is based on a close collaboration with prominent Professors Dr. Rafael Maldonado and Dr. Olga Valverde from the Laboratory of Neuropharmacology in Barcelona, Spain.
