Intra-operative mapping and language protection in glioma

The demand for acquiring different languages has increased with increasing globalization. However, knowledge of the modification of the new language in the neural language network remains insufficient. Although many details of language function have been detected based on the awake intra-operative mapping results, the language neural network of the bilingual or multilingual remains unclear, which raises difficulties in clinical practice to preserve patients' full language ability in neurosurgery. In this review, we present a summary of the current findings regarding the structure of the language network and its evolution as the number of acquired languages increased in glioma patients. We then discuss a new insight into the awake intra-operative mapping protocol to reduce surgical risks during the preservation of language function in multilingual patients with glioma.

Automated summary

The demand for acquiring different languages has increased with increasing globalization, but the neural language network of bilingual or multilingual individuals remains unclear, posing challenges in neurosurgical practice. Studies show that the structure of the language network changes as the number of acquired languages increases in glioma patients.
