intervention for the mentally disturbed. In the late 1930s, he worked closely with the neurosurgical team of the Racconigi Hospital near Turin to establish it as an early and influential centre for the adoption of leucotomy in Italy. Development Leucotomy was first undertaken in 1935 under the direction of the Portuguese neurologist (and inventor of the term psychosurgery) António Egas Moniz. First developing an interest in psychiatric conditions and their somatic treatment in the early 1930s, Moniz apparently conceived a new opportunity for recognition in the development of a surgical intervention on the brain as a treatment for mental illness. Frontal lobes The source of inspiration for Moniz's decision to hazard psychosurgery has been clouded by contradictory statements made on the subject by Moniz and others both contemporaneously and retrospectively. The traditional narrative addresses the question of why Moniz targeted the frontal lobes by way of reference to the work of the Yale neuroscientist John Fulton and, most dramatically, to a presentation Fulton made with his junior colleague Carlyle Jacobsen at the Second International Congress of Neurology held in London in 1935. Fulton's primary area of research was on the cortical function of primates and he had established America's first primate neurophysiology laboratory at Yale in the early 1930s. At the 1935 Congress, with Moniz in attendance, Fulton and Jacobsen presented two chimpanzees, named Becky and Lucy who had had frontal lobectomies and subsequent changes in behaviour and intellectual function. According to Fulton's account of the congress, they explained that before surgery, both animals, and especially Becky, the more emotional of the two, exhibited "frustrational behaviour"that is, have tantrums that could include rolling on the floor and defecatingif, because of their poor performance in a set of experimental tasks, they were not rewarded. Following the surgical removal of their frontal lobes, the behaviour of both primates changed markedly and Becky was pacified to such a degree that Jacobsen apparently stated it was as if she had joined a "happiness cult". During the question and answer section of the paper, Moniz, it is alleged, "startled" Fulton by inquiring if this procedure might be extended to human subjects suffering from mental illness. Fulton stated that he replied that while possible in theory it was surely "too formidable" an intervention for use on humans. Moniz began his experiments with leucotomy just three months after the congress had reinforced the apparent cause and effect
