英文摘要 | This research investigated the association of Mandarin F0 contour perception with the superior temporal gyrus (STG) and the inferior frontal gyrus (IFG) when tones input from the right ear. Adopted in this study are two types of tones: sinewave pitches (SW) and lexical tones (LX). LX refers to tones with, and SW, tones without, vocalic information. Functional magnetic resonance imaging (fMRI) data of the present study shows that LX perception, compared with SW perception, had additional activations at the left IFG and more noticeable activations at the right IFG. The additional activations at the left IFG imply association with the perception of vocalic information of LX. Despite the differences, SW and LX perception shared common activations at the left STG and the right IFG, suggesting that vocalic information plays no key role in tonal perception. The involvement of the left STG supports the phonemic feature of Mandarin tones. The present investigation reveals that solely the left STG of the brain cannot achieve the processing of Mandarin tones, and the role of the right IFG cannot be ignored. |
