The statement provided in the question is inaccurate. Performing lobotomies was not a belief held by ancient Greek physicians to release inner spirits causing mental illness. Lobotomy is a medical procedure that involves surgically altering the connections in the brain's prefrontal lobe and was not practiced in ancient Greece.
Instead, ancient Greek physicians, such as Hippocrates, focused on naturalistic explanations for mental illnesses. They believed in the balance of bodily fluids, known as humors, and their influence on health. They thought that an imbalance of these humors could lead to mental or physical ailments.
Therefore, the accurate answer is neither "OT" nor "OF" as the statement regarding lobotomies and releasing inner spirits is not aligned with the practices or beliefs of ancient Greek physicians.
