Psilocin, the psychoactive metabolite of psilocybin, increases BDNF abundance in human cortical neurons derived from induced pluripotent stem cells via the 5-HT2A receptor. Transcriptomic profiling shows gene expression changes that prime neurons for neuroplasticity. Morphologically, psilocin enhances neuronal complexity and increases synaptic proteins, especially in the postsynaptic compartment. Functionally, it leads to increased excitability and enhanced synaptic network activity. These findings suggest psilocin induces a state of enhanced neuronal plasticity, which may explain its therapeutic potential in neuropsychiatric disorders involving synaptic dysfunction.
