Non-Hallucinogenic Psychedelic Analog Reverses Effects of Stress in Mice

A single dose of tabernanthalog (TBG), a non-hallucinogenic psychedelic analog, corrects stress-induced behavioral deficits, including anxiety and cognitive inflexibility, in mouse models. Additionally, the compound promoted neurogenesis and restores neural circuits in brain areas damaged by stress.
