【摘要】 目的利用磁共振脑功能成像技术来验证简单乘法运算与三重编码模型是否匹配。方法对13名本科生志愿者采用基于光学的单数乘法任务进行提问,同时运用1.5 T的Marconi磁共振成像系统采集其脑部的血氧水平依赖性功能成像数据。运用SPM99软件进行t检验,以获取单数运算时的脑功能图像。结果明显激活左侧额中回、额下回、角回、视觉联合皮质区,两侧顶上小叶。结论单数乘法运算与三重编码模型相匹配。更多还原

【Abstract】 Objective To verify the triple code model by the experiment of single digital multiplication calculation with functional MRI(fMRI) technology.Methods Thirteen volunteers undergone the task of multiplication in the form of block-design.The fMRI data were analyzed by SPM99 software with statistic t-test to generate the activation map.Results The left superior frontal gyre(SFG),the right MFG,IFG,SPL,AG,the right SPL,precentral gyre(PCG) and bilateral visual association cortex were activated in the multiplition tasks.Conclusion The results are almost consistent with the triple code model.更多还原
