Leucotomized refers to a medical procedure that involves the surgical severing of connections in the brain's frontal lobes, primarily to alleviate severe mental illness symptoms. This procedure, known as lobotomy, was historically used to treat conditions such as schizophrenia and severe depression but has largely fallen out of favor due to ethical concerns and the development of more effective treatments. The term "leucotomy" is often used interchangeably with "lobotomy," though it specifically denotes the disconnection of white matter pathways in the brain.
