This review examines how psychedelic drugs like psilocybin and LSD affect the brain, particularly through serotonin receptors. While these compounds can produce psychosis-like symptoms similar to schizophrenia, they also promote brain plasticity and growth of neural connections. The article discusses whether psychedelics could potentially treat negative symptoms and cognitive problems in schizophrenia patients, despite their mind-altering properties, possibly through lower doses or non-hallucinogenic alternatives.
