Abstract
Zebrafish is gaining popularity in behavioral neuroscience in general and in alcohol research in particular. Alcohol is known to affect numerous molecular mechanisms depending on dose and administration regimen. Prominent among these mechanisms are several neurotransmitter systems. Here we analyze the responses of the dopaminergic and serotoninergic neurotransmitter systems of zebrafish to acute alcohol treatment (1 h long exposure of adult fish to 0.00%, 0.25%, 0.50%, or 1.00% ethyl alcohol) by testing the concentration of dopamine, its metabolite DOPAC, and serotonin and its metabolite 5-HIAA from whole brain extracts. We utilize a sensitive HPLC method and describe significant alcohol induced changes in zebrafish for the first time. We show that dopamine significantly increased in a quasi-linear dose dependent manner, DOPAC showed a smaller apparent increase which was non-significant, while both serotonin and 5-HIAA showed a significant increase only in the highest acute dose group. We discuss the methodological novelty of our work and theorize about the implications of the neurotransmitter level changes from a behavioral perspective.
