We present a 63-year-old, left-handed, healthy man who was identified as having schizencephaly [1] in the left hemisphere (Fig. 1), without any history of seizure or developmental problems. Comprehensive speech/language studies revealed mild dysarthria with limited lateral tongue movement and competent language ability except mild difficulty in repeating sentences. The data of fMRI showed the preponderant involvement of the right frontal in sentence completion and bilateral temporal areas in verb generation task (Fig. 2), indicating the dissociative and reversed intrahemispheric activation of language [2]. The developmental anomaly may have affected this peculiar language representation in the brain of this patient.

精神分裂症患者的分离语言表征

我们介绍了一名 63 岁、左撇子、健康的男性，他被确定患有左半球裂脑症 [1]（图 1），没有任何癫痫发作或发育问题的病史。综合言语/语言研究显示轻度构音障碍，舌侧向运动受限，语言能力良好，但重复句子有轻微困难。fMRI 的数据显示右额叶在句子完成和双侧颞区在动词生成任务中占主导地位（图 2），表明语言的分离和反向半球内激活 [2]。发育异常可能影响了该患者大脑中这种特殊的语言表达。
