The standard five-hole operant chamber, as used for the RGTreward or time-out model. (A) Side view of a Med Associates five-hole box. These chambers are modular and can be configured for multiple behavioral paradigms and manipulations, hence the arm assembly for drug self-administration/microdialysis and additional levers visible. However, these components are not necessary for the RGT. (B) A close-up of the standard five-hole array showing stimulus light location and infrared beam.
