单词	leucotomy
释义	leucotomy /luːˈkɒtəmi / noun (plural leucotomies) [mass noun] The surgical cutting of white nerve fibres within the brain, especially prefrontal lobotomy, formerly used to treat mental illness.This operation, also called prefrontal leucotomy or standard lobotomy, was performed widely, and soon its beneficial as well as its detrimental effects became apparent.... But back in 1936, when Freeman performed his first leucotomy, the only alternative treatment for severe mental illness was prolonged institutionalisation, and the procedure did seem to liberate many patients from this fate. The number of lobotomies, or leucotomies, fell dramatically after the 1950s, as drugs became available, especially for schizophrenia.
