A lobotomy is a surgical procedure in which part of a patient's brain is severed. Once used to treat mental illness, the procedure is now deemed harmful and fell out of use in the 1960s.
On October 26, 1985, in the nightmarish alternate timeline where the alternate Emmett Brown had been committed, Doc disguised himself and traveled to the County Asylum. Pretending to be his counterpart's distant cousin, Mr. Von Braun, Doc bribed the asylum nurse to allow him to talk with his alternate self. He discovered that, at some point after being committed, his counterpart had little brain function, and believed he had been lobotomized.
Doc's assessment of the situation proved to be incorrect, however, as it turned out that Doc's counterpart had used a practice used by some Eastern religions which allowed him to shut off certain higher functions of his brain. He did this to protect the secret of his time travel chamber, which was in the possession of BiffCo.
