尽管在成人灰质中已经证明了依赖于经验的结构变化,但几乎没有证据表明白质中存在这种变化。使用扩散成像,我们检测到在复杂的视觉运动技能训练后,顶内沟下方白质的分数各向异性(微观结构的一种测量方法)局部增加。这为健康成人大脑中白质结构的训练相关变化提供了第一个证据。
Although experience-dependent structural changes have been demonstrated in adult gray matter, there is little evidence for such changes in white matter. Using diffusion imaging, we detected a localised increase in fractional anisotropy, a measure of microstructure, in white matter underlying the intraparietal sulcus, following training of a complex visuo-motor skill. This provides the first evidence for training related changes in white matter structure in the healthy human adult brain.
