Five labs ran the same psilocybin experiment on mice (2 mg/kg, both sexes, about 200 mice per test). A green square means that lab found the effect.

Lab-by-lab pattern for the depression test is approximate ("2 of 5 labs, in one of two assays"); per-lab results for the other tests were reported as consistent across labs. The authors stress this is not evidence psilocybin fails in humans.
