The circling training rat model as a behavioral teratology test
The properties of circling training (CT) for detecting behavioral teratologic drug-induced effects was evaluated by prenatal administration of two behavioral teratogenic drugs: vitamin A (80,000 IU/kg/day) and haloperidol (2.5 mg/kg/day). The circling training was started at 30 days of age and perfo...

| Sumario: | The properties of circling training (CT) for detecting behavioral teratologic drug-induced effects was evaluated by prenatal administration of two behavioral teratogenic drugs: vitamin A (80,000 IU/kg/day) and haloperidol (2.5 mg/kg/day). The circling training was started at 30 days of age and performed for 8 days in an automated apparatus. Statistically significant differences between drug-treated and control animals regarding the measured response (turns per minute) were found. Two components may affect the response measured by the CT: associative learning and motor performance. The incidence of these components was discriminated with behavioral and mathematical approaches. In the experimental conditions used the most affected parameter was motor performance. The results indicate that CT can be used as an instrumental conditioning test where the quantifiable endpoint is the on-going motor performance. Further applications of the CT for neurochemical evaluation of drug induced effects are also discussed. © 1991. |
