摘要
目的:探讨面孔识别中,梭状回视觉加工的基本功能。材料和方法:12位大学生对图片进行名人-非名人和男-女性别判断,以功能磁共振采集数据,AFNI软件处理数据。统计方法,首先画感兴趣区,计算个体感兴趣区的脑激活,用ANOVA和t-test进行组分析。结果:名人判断或性别判断都明显激活了梭状回,对左右侧分刖进行名人与性别的差异性检验,差异性均未达到显著性水平。结论:梭状回不区分名人与非名人,不区分男女性别,激活取决于刺激的物理属性,如新颖程度、鲜明性等客观因素,其功能可能是非特异性的。
Purpose： To study the basic function of the visual processing of fusiform gyrus in face perception.Materials and Methods： We requried twelve college students to judge the pictures of famous people or non - famous people and the gender of the face. All the datas were summaried by fMRI and processed by the soft of AFNI. Results： No matter to make the identity or gender judgement, fusiform gyrus were activated. However, the volume of the activation and center coordinate were just little difference. Conclusion： The activation of fusiform gyrus were due to physical property of the stimulatives, such as the novelty and trenchancy, but not the content of the material .
