IN VIVO PROTON MAGNETIC RESONANCE SPECTROSCOPY (MRS) OF BREAST CANCER

引言：大脑活动与阅读的关系 表现进行了检查，以检验这一假设，即诵读困难涉及 一个特定的视觉通路的缺陷，称为M通路， 从眼睛到大脑 方法：功能磁共振成像 （功能磁共振成像）被用来测量大脑活动的障碍和控制 受试者处于旨在优先刺激M 通路 结果：阅读障碍者的活动减少， 在初级视觉皮层（V1）和次级视觉皮层（V2）中， 皮质视觉区（MT+），被认为是接收强烈的M 路径输入 最重要的是， 阅读速度和大脑活动之间的个体差异。 结论：这些结果支持M通路的假设 阅读障碍的异常，并意味着一个强大的关系， M通路的完整性和阅读能力。

Introduction: The relationship between brain activity and reading performance was examined to test the hypothesis that dyslexia involves a deficit in a specific visual pathway, known as the M pathway, from the eye to the brain. Methods: Functional magnetic resonance imaging (fMRI) was used to measure brain activity in dyslexic and control subjects in conditions designed to preferentially stimulate the M pathway. Results: Dyslexics showed reduced activity compared to controls both in primary visual cortex (V1) and in a secondary cortical visual area (MT+) that is believed to receive a strong M pathway input. Most importantly, significant correlations were found between individual differences in reading rate and brain activity. Conclusions: These results support the hypothesis for an M pathway abnormality in dyslexia and imply a strong relationship between the integrity of the M pathway and reading ability.
