Figure Lengend Snippet: (A) Steps to build the apparatus (Stage VII). The base of the apparatus is a standard modular operant test chamber with modified top for rat (ENV – 008CT). (B) Automatic social-choice self-administration apparatus. (Top left panel) The picture represents the apparatus with the configuration described in this protocol and detailed measurements. Food and water are available during the self-administration and choice sessions and are attached in the front door. Legend: 1. Retractable lever 1; 2. Retractable lever 2; 3. Inactive lever; 4. Tone; 5. House light white; 6. House light red; 7. Cue light white; 8. Food magazine (optional); 9. Food receptacle (optional); 10. Pump; 11. Door; 12. Barrier; 13. Fan. 14. SmartCtrl Connection Panel (8 in/16 out). All measurements are in cm. (Bottom left panel) Social apparatus enclosed in the Med-Associates cubicle. Magnification of the modified cubicle for an easy access to the left retractable active lever. (Right panel) Different barrier types. Top panel: barrier for female rats; bottom: barrier for male rats (all measurements are in cm).
