Cortical organization for receptive language functions in Chinese, English, and Spanish: a cross-linguistic MEG study.

摘要: Chinese differs from Indo-European languages in both its written and spoken forms. Being a tonal language, tones convey lexically meaningful information. The current study examines patterns of neurophysiological activity temporal temporoparietal brain areas as speakers two (Spanish English) Mandarin-Chinese were engaged spoken-word recognition task that is used clinically for the presurgical determination hemispheric dominace receptive language functions. Brain magnetic activation profiles obtained 92 healthy adult volunteers: 30 monolingual native Mandarin-Chinese, 20 Spanish-speaking, 42 American English. Activation scans acquired different whole-head MEG systems using identical testing methods. Results indicate (a) degree asymmetry duration regions was reduced group, (b) proportion individuals who showed bilaterally symmetric significantly higher this (c) group differences functional first noted after initial sensory processing word stimuli. Furthermore, primarily due to greater right region suggesting increased participation Mandarin-Chinese.
