| ObjectiveAlthough voice familiarity and language proficiency are considered to be very important attributes of the human verbal voice, little is known about the neural basis of voice familiarity, and whether language proficiency is the most important factor to different language perception is unclear too. In the present study, bfMRI and efMRI are going to be employed to define the cerebral activation patterns concerned with voice familiarity and to discuss the significance of language proficiency in bilingual perception in Chinese-English late bilingual subjects, so we would set foundation for building the neuroimaging model of language perception in the end. MethodsThirteen Chinese healthy male subjects (mean age 26.1 years, SD=2.9years) participated in the study. All subjects were right-handed,by division reproduction late bilinguals and Han nationality. When functional scanning, by meams of hearing, all subjects were required to finish familiar or unfamiliar judgement tasks of Chinese and English sentences spoken by their friends or strangers, and the behavioral results were recorded by Presentation software in the same time. Block design and event-related design were both performed in this experiment respectively. Every subject should fulfill five run tasks when functional scanning, two were block design and the other event-related design. Based on BOLD efficacy, functional images with EPI were collected using a 1.5T MRI (GE Systems, USA), and were analyzed using statistical parametric mapping 99 (SPM99). The goal was to identify the cerebal activation... |
