The olfactory bulbectomized rat as a model of depression
Polish Journal of Pharmacology and Pharmacy
|September 1, 1984
Summary
Bilateral olfactory bulbectomy in rats causes behavioral deficits, which can be improved by antidepressants. This model aids in discovering new antidepressants and understanding their mechanisms.
Area of Science:
- Neuroscience
- Behavioral Pharmacology
Background:
- Bilateral olfactory bulbectomy in rats induces significant behavioral alterations.
- These alterations include deficits in active and passive avoidance learning and hyperactivity in novel environments.
Purpose of the Study:
- To summarize the behavioral effects of olfactory bulbectomy in rats.
- To present evidence for the efficacy of antidepressants in mitigating these deficits.
- To evaluate the utility of the olfactory bulbectomized rat model for antidepressant drug discovery and mechanism elucidation.
Main Methods:
- Review and summarization of existing evidence on the behavioral effects of bilateral olfactory bulbectomy in rats.
- Analysis of studies demonstrating the effects of chronic antidepressant administration on these behaviors.
Main Results:
- Olfactory bulbectomy leads to impaired active and passive avoidance behaviors.
- Hyperactivity is observed in bulbectomized rats when exposed to stressful novel environments.
- Chronic administration of antidepressants specifically attenuates these behavioral deficits.
Conclusions:
- The olfactory bulbectomized rat serves as a valuable model for identifying potential antidepressant compounds.
- This model provides insights into the mechanisms of action of antidepressant drugs.
