Effects of chlorpromazine on continuous avoidance behavior in mice
Pharmacology, Biochemistry, and Behavior
|September 1, 1982
Summary
Mice can now learn tasks using aversive stimuli, similar to rats. This new method in operant behavioral pharmacology offers advantages for researchers using mice.
Area of Science:
- Behavioral pharmacology
- Neuroscience
- Animal models
Background:
- Operant conditioning is a key method in behavioral pharmacology.
- Mice are increasingly used in research due to their genetic tractability.
- Previous methods focused on appetitive reinforcement schedules.
Purpose of the Study:
- To adapt head-movement-based operant conditioning for aversive reinforcement in mice.
- To validate the use of mice in aversive operant schedules.
- To compare mouse and rat responses to a known drug (chlorpromazine).
Main Methods:
- Modified a head-movement-detecting apparatus for aversive shock delivery.
- Established a continuous avoidance operant schedule in mice.
- Administered chlorpromazine and observed behavioral effects.
Main Results:
- Mice successfully acquired the continuous avoidance schedule.
- Behavioral effects of chlorpromazine in mice mirrored those in rat models.
- The methodology proved effective for aversive operant conditioning in mice.
Conclusions:
- Head-movement-based operant conditioning is effective for aversive schedules in mice.
- Mice can serve as a viable alternative to rats in aversive operant behavioral pharmacology.
- This expands research opportunities using mice in drug discovery and behavioral studies.
