Panlab/Harvard Apparatus Place Preference Box is a standard experimental chamber for automated assessment of conditioned place preference and aversion in rodents, two tests widely used for screening the reinforcing properties of drugs (or natural stimuli) as well as for investigating the brain neurobiological systems implicated in reward and addition.

The experimental box consists of two Perspex compartments of the same size interconnected by a central grey corridor. The compartments can be differentiated by both visual and tactile cues: the color of the walls in each compartment (white or black) and the texture of the floors (smooth or rough). The box is provided with transparent frontal walls which may be covered with extractable opaque covers (included). Manually operated sliding doors are provided to manage the access to the two compartments from the corridor.

The experimental box can be supplied with or without automatic animal position detection system. The automated animal position detection is carried out by a weight transducer system which is associated to the PC-based control software PPCWin.
