我们的目的是识别与字形缓冲区缺陷相关的神经解剖区域,字形缓冲区是拼写系统的工作记忆组件,在生产过程中保存字母标识的序列。我们在中风发作后 48 小时内通过各种拼写测试以及磁共振扩散加权成像和灌注加权成像对 331 名左半球缺血性中风患者进行了评估。体素统计图显示,额叶后部、下额和顶叶皮层、前额叶皮层下方的皮层下白质、枕外侧回或尾状核中的体素缺血与拼写时维持字母同一序列的损害有关。
We aimed to identify neuroanatomical regions associated with deficits to the graphemic buffer, a working memory component of the spelling system that holds the sequence of letter identities during production. We evaluated 331 patients with left hemisphere ischemic stroke with various spelling tests and magnetic resonance diffusion-weighted imaging and perfusion-weighted imaging, within 48 hours of stroke onset. A voxel-wise statistical map showed that ischemia in voxels in posterior and inferior frontal and parietal cortex, subcortical white matter underlying prefrontal cortex, lateral occipital gyrus, or caudate was associated with impairment in maintaining the sequence of letter identities while spelling.
