Typically animal models are created that are thought to overlap with the mechanism of the disorder they're studying. Sometimes this is done genetically, sometimes by toxic drugs. In this case, neural damage is induced through methamphetamine, this is thought to damage some of the same neurons that schizophrenia affects. The results may or may not transfer to the actual disease in human. There's a reason most animal based research doesn't pan out in the end.
