A second case after Leborgne is what solidified Broca's beliefs that our speech function was localized. Lazare Lelong was an 84-year-old grounds worker who was being treated at Bicêtre for dementia. He had also lost the ability to speak other than five simple, meaningful words - these included his own name, "yes", "no", "always" as well as the number "three". After his death his brain was also autopsied. Broca found a lesion that encompassed much the same area as had been affected in Leborgne's brain. This finding concluded that a specific area controlled our ability to produce meaningful sounds, and when it is affected, one can lose their capability to communicate. For the next two years, Broca went on to find autopsy evidence from twelve more cases in support of the localization of articulated language. Broca published his findings from the autopsies of the twelve patients in his paper, “Localization of Speech in the Third Left Frontal Cultivation” in 1865. His work inspired others to perform careful autopsies with the aim of linking more brain regions to sensory and motor functions. Although history credits this discovery to Broca, another French neurologist, Marc Dax, had made similar observations a generation earlier. Based on his work with approximately forty patients and subjects from other papers, Dax presented his findings at a 1836 conference of southern France physicians in Montpellier. Unfortunately, Dax died soon after this presentation and it was not reported or published until after Broca made his initial findings. Accordingly, Dax's and Broca's conclusions that the left frontal lobe is essential for producing language are considered to be independent.
