3 Case Study- Leborgne 51-year-old patient with multiple neurological problems Without any productive speech for many year Could only produce a single repetitive syllable, ‘tan’ Could vary the intonation of the sound but was not able to produce any recognizable words or phrases Broca saw Leborgne's lack of speech as a test case for the question of language localization in the frontal lobes Leborgne died of his ailments several days later A lesion was found on the surface of the left frontal lobe as Broca had suspected

4 CT Scan of Lebrogne

5 Case Study- Lelong 84 years old Also exhibited reduced productive speech as the result of a stroke 1 year before Could say only five words, ‘oui’ (‘yes’), ‘non’ (‘no’), ‘tois’ (a mispronunciation of ‘trois’ (‘three’) which he used to represent any number), ‘toujours’ (‘always’) and ‘Lelo’ (a mispronunciation of his own name) At autopsy, Lelong was also found to have a lesion in approximately the same region of the lateral frontal lobe as the first case
