Transplanting Human Poo from Depressed Patients Can Induce Depression-Like Behavior in Mice

What was said

"If you take poo from people with major depressive disorder or with schizophrenia and you put them into mice compared to poo from healthy people, you can induce what's called the behavioral phenotype. Basically, you can make a mouse behave as if it has depression or schizophrenia, you can see some of the biochemical changes."

Professor Felice Jacka reveals that fecal transplants from humans with mental disorders can cause mice to display similar behavioral symptoms. This demonstrates that gut microbes may causally drive mental illness, not just correlate with it, fundamentally challenging the notion that depression is purely psychological.
