THE SELECTIVE SEROTONIN REUPTAKE INHIBITORS AND BEHAVIOUR OF ADULT DANIO RERIO IN EXPERIMENTS

Area of Science:

• Neuroscience
• Behavioral Science
• Pharmacology

Background:

• Depression is a prevalent mental disorder affecting various age groups.
• Its pathogenesis involves complex morphofunctional and pathopsychological components.
• Laboratory animals are crucial for studying depression and developing treatments.

Purpose of the Study:

• To investigate the behavioral effects of selective serotonin reuptake inhibitors (SSRIs) in a zebrafish model of depression.
• To elucidate behavioral differences induced by fluoxetine and sertraline in Danio rerio.

Main Methods:

• Zebrafish (Danio rerio) were used as an experimental model for depression.
• Behavioral observations were conducted before and after administration of fluoxetine and sertraline.
• Changes in swimming activity, social interaction, and body posture were recorded.

Main Results:

• Before SSRI administration, fish exhibited hyperactivity and aggressive behavior when separated into pairs.
• Fluoxetine and sertraline altered fish behavior, reducing hyperactivity.
• On day three, sertraline-treated fish showed improved swimming levels, while fluoxetine-treated fish remained at the bottom.
• By day five, some sertraline-treated fish displayed abnormal body positioning.

Conclusions:

• SSRIs, specifically fluoxetine and sertraline, induce observable behavioral changes in zebrafish.
• Zebrafish serve as a viable model for studying the effects of antidepressants.
• Differential responses to fluoxetine and sertraline suggest distinct mechanisms of action or efficacy in this model.
