Abstract

The recent renaissance in research on psychedelics such as psilocybin has highlighted their therapeutic potential including their lasting influences on brain function. Here we report that a single systemic administration of the serotonergic psychedelic psilocybin can durably promote social behaviour in the Cntnap2-knockout mouse model of autism. This effect can be blocked by pharmacological inhibition of DNA methyltransferase I, indicating an epigenetic mechanism underlying the long-lasting effect of psilocybin.
