我们研究了耳聋和手语经验如何影响人类的大脑，通过比较先天性耳聋的签名者（n = 30），听力本地签名者（n = 30）和听力标志幼稚对照组（n = 30）的神经解剖结构。基于体素和基于表面的形态测量结果均显示视觉皮层（灰质）、右额叶（脑回化）和左Heschl脑回（白色物质）中与视觉相关的结构变化。比较还揭示了与终生手语经历相关的变化：聋人和听力正常的手语者的左前颞叶和左枕叶内表面积扩大，右枕叶皮质厚度减少。这些大脑区域的结构变化可能与处理手语的神经网络的适应有关（例如面部和身体运动的视觉感知）。听力母语者也有独特的神经解剖学变化（例如运动前区的回旋减少），这可能是由于他们一生都在使用口语和手语。
We investigated how deafness and sign language experience affect the human brain by comparing neuroanatomical structures across congenitally deaf signers (n = 30), hearing native signers (n = 30), and hearing sign-naïve controls (n = 30). Both voxel-based and surface-based morphometry results revealed deafness-related structural changes in visual cortices (grey matter), right frontal lobe (gyrification), and left Heschl’s gyrus (white matter). The comparisons also revealed changes associated with lifelong signing experience: expansions in the surface area within left anterior temporal and left occipital lobes, and a reduction in cortical thickness in the right occipital lobe for deaf and hearing signers. Structural changes within these brain regions may be related to adaptations in the neural networks involved in processing signed language (e.g. visual perception of face and body movements). Hearing native signers also had unique neuroanatomical changes (e.g. reduced gyrification in premotor areas), perhaps due to lifelong experience with both a spoken and a signed language.
