In a zebrafish model of depression, both synthetic psilocybin and an extract from psychedelic mushrooms reversed stress-induced behavioral changes, making the fish behave similarly to non-stressed controls. The mushroom extract produced more neurotransmitter precursors in the brain than synthetic psilocybin, though no significant behavioral differences between the two treatments were observed. Whole-brain metabolomics revealed increases in GABA, vitamin B6, glutamine, and NADH, along with a decrease in xanthosine, suggesting possible neuroplastic effects. This work demonstrates the potential of zebrafish models for studying psychedelic compounds.
