Effects of hallucinogenic agents mescaline and phencyclidine on zebrafish behavior and physiology
چکیده انگلیسی

Mescaline and phencyclidine (PCP) are potent hallucinogenic agents affecting human and animal behavior. As their psychotropic effects remain poorly understood, further research is necessary to characterize phenotypes they evoke in various animal models. Zebrafish (Danio rerio) are rapidly emerging as a new model organism for neuroscience research. Here, we examine the effects of mescaline (5-20 mg/l) and PCP (0.5-3 mg/l) in several zebrafish paradigms, including the novel tank, open field and shoaling tests. Mescaline and PCP dose-dependently increased top activity in the novel tank test, also reducing immobility and disrupting the patterning of zebrafish swimming, as assessed by ethograms. PCP, but not mescaline, evoked circling behavior in the open field test. At the highest doses tested, mescaline markedly increased, while PCP did not affect, zebrafish shoaling behavior. Finally, 20 mg/l mescaline did not alter, and 3 mg/l PCP elevated, whole-body cortisol levels. Overall, our studies indicate high sensitivity of zebrafish models to hallucinogenic compounds with complex behavioral and physiological effects.

► Mescaline and phencyclidine are potent hallucinogenic drugs. ► Zebrafish are becoming a promising model for investigating hallucinogenic compounds. ► Mescaline (20 mg/l) increases top swimming and shoaling behavior in zebrafish. ► Phencyclidine (3 mg/l) induces circling and elevated cortisol levels in zebrafish.
