      Abstract

      In a series of papers which appeared in 1906, Pierre Marie advanced a new concept of aphasiology against the classical view based on functional localization of cerebral cortex. He denied the role of Broca’s area in language function and proposed as the center for articulation “zone lenticulaire,” the lesion of which causes anarthria. But his illustration of “zone lenticulaire” which appears repeatedly in his papers dealing with aphasia, is anatomically incorrect since the most important portions of Broca’s area, opercular part and triangular part of the inferior frontal gyrus are missing in his illustration. The detailed anatomical investigation of Marie’s illustrations reveals that he repeated the same errors in identifying rolandic and frontal opercula. But the similar mistake of identifying these opercula is also seen in Dejerine’s “Anatomie des Centres Nerveux.”

      Pierre Marie’s “Zone Lenticulaire”

      The cardinal theoretical base of his new concept of aphasiology was based on 2 anatomo-pathological findings; first, lesions of the Broca’s area did not necessarily cause Broca’s aphasia and second, there were reports of patients showing Broca’s aphasia without any destructive lesion of the Broca’s area. To explain the second point, he showed the famous illustration of “zone lenticulaire” which was the site of anarthria, and also showed cases of Broca’s aphasia with lesion situated in this zone. He also described a case of small hemorrhagic lesion in this zone which had caused only anarthria without true aphasia. According to him, a lesion within the “zone lenticulaire” caused the patient severe anarthria but he did not show aphasia because his Wernicke’s area was intactly preserved, only the lesion of which was thought to produce aphasia.
