Fig. 5. Dejerine’s error in identifying the triangular part of the inferior frontal gyrus (corrected anatomical names are given with arrows; modified from [8]).

      Consequently, as to the identification of triangular part of the inferior frontal gyrus including Area 45 of Brodmann in the horizontal brain slice, Dejerine shared the same error with Marie. As shown above, Marie showed in his first paper [1] a case of his own who had no language impairment in spite of a lesion on the Broca’s area. The site of the lesion of this case was erroneously located on the triangular part by Marie, and the real site of the lesion was on the anterior part of the inferior frontal gyrus, probably Area 46 of Brodmann. Dejerine did not point out the misidentification of the site of the lesion of this case, since he had made the same error of identification of triangular part in the horizontal brain slice [8]. It seems rather very strange that both the experts in clinicopathological studies of aphasia had shared the same mistake. Marie’s papers finally elicited the famous aphasia debate in 1908, but the problem of incorrect location of the Broca’s area, especially of Area 45, was never discussed either by Marie or by Dejerine, because not only Marie but also Dejerine had made the same error in identifying Area 45 of the Broca’s area in the horizontal brain slice.

      Abstract

      In 1943, Tsuneo Imura, a neuropsychiatrist at Tokyo University, proposed a new aphasic syndrome and designated it as Gogi (word meaning) aphasia. According to Imura, it is characterized by (1) difficulty in comprehending spoken words despite good perception of sound, (2) disorders of expression due to loss of vocabulary and verbal paraphasia, (3) preserved ability of repetition, and (4) selective difficulty in reading and writing kanji (Japanese logographic character) with preserved ability of reading and writing kana (Japanese syllabic character). To be more specific, the difficulty in comprehending spoken words in Gogi aphasia is limited to substantive words as the name of the syndrome indicates, while comprehension of syntax remains unimpaired. Preserved repetition ability cannot be simply regarded as an automatic response, that is, echolalia, because the patient’s attitude in repeating was quizzical, picking up the particular word he did not comprehend. Imura vaguely attributed the responsible lesion to the second and third temporal gyri on the left side. Although the general pattern of the syndrome can be placed in the category of transcortical sensory aphasia, its uniqueness as the syndrome still stands out. Another uniqueness of the syndrome is its characteristic pattern of dissociated kanji-kana difficulty in reading and writing. This linguistic symptomatology observed in Gogi aphasia was first introduced to the western academic world on a German neuropsychiatric journal by Panse and Shimoyama СКАЧАТЬ
