for rats, for mice
The APA is a circular metal arena shock grid underneath a rotating arena. The subjects are allowed to explore the arena while avoiding a prohibited sector using visual cues in and around the arena. Punishment in the form of shock is delivered to the subject if it enters the prohibited sector. Passive avoidance is observed when the arena is not rotating while active avoidance is observed when the arena is rotating.
