计算任务男女性别差异的fMRI研究
首发时间:2006-10-17
摘要:目的:用fMRI(functional magnetic resonance imaging)探讨男女不同性别在计算任务时脑活动的差异。材料和方法:对10例男性、8例女性年青受试者进行简单及复杂任务的功能MRI扫描,采用SPM2软件进行数据分析和脑功能区定位。结果: 计算任务中男女主要激活区域均为额前区、顶叶、枕叶及小脑,男性额前区及顶叶等计算功能区激活范围较女性广,其中以复杂计算为著。结论:相同的计算任务,男性激活的脑功能区范围多于女性。

The difference of calculation in functional MRI between female and male
Abstract:Objective: To explore the difference of the activation areas of brain in calculation between male and female with functional MRI. Methods: Functional MR images were acquired in 18 healthy young subjects when they received simple calculation and complex calculation experiment. SPM2 was used to process data and localize functional areas of brain. Results: Prefrontal cortex , parietal lobe, occipital lobe and cerebellum are activated during simple calculation and complex calculation task in male and female, The activated areas(means the function calculation areas ,Prefrontal cortex and parietal lobe) are larger in male than that in the female ,especially in the complex calculation task . Conclusion: More areas of brain are activated in male than that in female in the same calculation task.
Keywords: functional MRI calculation cortex;sex
