Conditioned Place Preference CPP System

Conditioned Place Preference (CPP)/ Conditioned Place Aversion (CPA)is a technique used to study unbiased place preference/aversion in mice or rats .Place conditioning is a form of Pavlovian conditioning and is used to measure a preference or aversion to an experience (e.g. drugs, amphetamines, heroin, etc).A typical protocol involves three (3) phases. Phase 1 is habituation; Phase 2 is conditioning of an association between the drug and a tactile and/or visual cue and Phase 3 is the final test where the animal is offered a choice between the drug associated cue and a neutral cue. If the drug induces CPP then the animal will spend more time close to the drug associated cue. If the drug induces CPA then the animal will spend less time close to the drug associated cue.

The CPP Frame is 32" L x16" W x 12" with 24 Photo beam sensors in Horizontal X and 12 Photo beam sensors in the Vertical Z axes. The arena (24"Lx12"Wx12"H)is divided into three sections. Section 1 (10" L x 12" W x 12" H) has Horizontal white stripes, Section 2 (4" L x 12" W x 12" H) is solid white (no stripes) , Section 3 (10" L x 12" W x 12" H)has Vertical white stripes. Varied floor textures are included as tactile cues for each section. Removable partitions are provided to segregate animal within a particular section. In a typical protocol, the drug is administered and the animal is confined to the drug assigned compartment for a fixed period. Animal is subsequently placed in the middle/neutral section of the apparatus .After a short delay, the partitions are removed so that the animal is free to move throughout the cage. At this point, the animal can exhibit place preference or place aversion by moving towards or away from the drug assigned compartment.
