Extensive data on cortical tongue representation were analyzed in 100 patients who underwent craniotomy and cortical mapping by electrical stimulation for surgical treatment of epilepsy. As noted in the literature, the tongue is extensively represented within the central nervous system with a highly organized sensorimotor system and the data from this study corroborate a large cortical representation of the human tongue over the postcentral gyrus. The tongue was found to have a clear somatotopic organization over the postcentral area and to be represented bilaterally to a significant degree. Furthermore, the tongue appears to have an asymmetrical sensory cortical representation, as cerebral dominance for speech is more extensively represented on the dominant hemisphere. Cortical tongue mapping has proved extremely useful in determining the point of junction of the central and Sylvian sulci, a crucial landmark during surgical cortical resections.
对100例因癫痫手术治疗而接受开颅手术和皮层电刺激图谱绘制的患者的大量关于皮层舌区表征的数据进行了分析。正如文献中所指出的,舌在中枢神经系统中有着广泛的表征,具有高度组织化的感觉运动系统,并且本研究的数据证实了人类舌在中央后回上有较大的皮层表征。研究发现,舌在中央后区有清晰的躯体定位组织,并且在很大程度上双侧都有表征。此外,由于语言的大脑优势在优势半球上有更广泛的表征,舌似乎有不对称的感觉皮层表征。皮层舌区图谱绘制已被证明在确定中央沟和外侧裂的交界点方面极其有用,这是手术皮层切除术中的一个关键标志。
