2 protocols using phm 120a

Operant Conditioning Chamber Setup for Drug Infusion Studies

Check if the same lab product or an alternative is used in the 5 most similar protocols

Standard operant conditioning chambers (28 × 21 × 21 cm; ENV-001; MED Associates, St. Albans, VT) with alternating aluminum and Plexiglas walls including a metal rod floor were located inside sound-attenuating chambers (ENV-018M; MED Associates, St. Albans, VT). A recessed food tray (5 × 4.2 cm) was located 2 cm above the floor in the center of one of the aluminum walls, and a response lever was located 6 cm above the floor on each side of the food tray. A white stimulus light (28 v, 3 cm diameter) was located 6 cm above each lever. The standard operant chambers were retrofitted with a counterbalance arm, swivel, and leash (PHM-110, PHM-115I and PHM-120A, respectively; MED Associates, St. Albans, VT). Drug infusions were delivered via a MED Associates infusion pump located outside of the sound-attenuating chamber (PHM-100; MED Associates, St Albans, VT). Responses were recorded and programmed consequences were controlled by a computer in an adjacent room equipped with Med-PC software (Med Associates, St. Albans, VT).

Operant Conditioning Chambers for Substance Self-Administration

Check if the same lab product or an alternative is used in the 5 most similar protocols

Standard operant conditioning chambers (28 × 21 × 21 cm; ENV-001; MED Associates, St. Albans, VT) with alternating aluminum and Plexiglas walls including a metal rod floor were located inside sound-attenuating chambers (ENV-018M; MED Associates, St. Albans, VT) were used in both d-amphetamine and food self-administration sessions. A recessed food tray (5 × 4.2 cm) was located 2 cm above the floor in the center of one of the aluminum walls, and a response lever was located 6 cm above the floor on each side of the food tray. A white stimulus light (28 v; 3 cm diameter) was located 6 cm above each lever. The standard operant chambers were retro-fitted with a counterbalance arm, swivel, and leash (PHM-110, PHM-115I and PHM-120A, respectively; MED Associates, St. Albans, VT). Drug infusions were delivered via a MED Associates infusion pump located outside of the sound-attenuating chamber (PHM-100; MED Associates, St Albans, VT). Responses were recorded and programmed consequences were controlled by a computer in an adjacent room equipped with Med-PC software (Med Associates, St. Albans, VT).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
