leukotome
Quick Summary
A leukotome is an instrument used in a surgical procedure called a lobotomy. A lobotomy involves severing nerve pathways in the brain to calm patients with severe mental illnesses like schizophrenia and bipolar disorder.12
The leukotome was developed by Portuguese neurophysician Ant\u00f3nio Egas Moniz. It was designed to disrupt the neural connections between the prefrontal cortex and the thalamus. This procedure was widely adopted in the mid-20th century due to a lack of other effective treatments for severely disturbed patients. However, with the advent of psychiatric medications in the 1950s, lobotomies became less common and are now rarely performed.2

lobotomy…created an instrument called a leukotome (leucotome), designed specifically to disrupt the tracts of neuronal fibres connecting the prefrontal cortex and thalamus of the brain. Moniz and Lima operated on nearly 40 patients by 1937; however, the results were mixed, with some patients improving, others showing no change in symptoms,…
