Reading activates a region within the left lateral occipitotemporal sulcus (OTS) known as the 'visual word form area' (VWFA). While several studies have investigated the impact of reading on brain structure through neuroplastic mechanisms, it has been recently suggested that individual differences in the pattern of the posterior OTS may predict reading skills in adults. In the present study, we first examined whether the structure and morphology and the anatomical connectivity of the left OTS are associated to reading ability. Second, we explored whether reading skills are predicted by the pattern of the left OTS. We found that reading skills were positively associated with increased connectivity between the left OTS and a network of reading-related regions in the left hemisphere. On the other hand, we did not observe an association between the pattern of the left OTS and reading skills. Finally, we found evidence that the morphology and the connectivity of the left OTS are correlated to its sulcal pattern.
阅读会激活左侧枕颞叶沟（OTS）内一个被称为“视觉词形区”（VWFA）的区域。虽然有几项研究通过神经可塑性机制研究了阅读对大脑结构的影响，但最近有人提出，OTS后部模式的个体差异可能预测成年人的阅读技能。在本研究中，我们首先检查了左侧OTS的结构、形态以及解剖连接性是否与阅读能力相关。其次，我们探讨了左侧OTS的模式是否能预测阅读技能。我们发现，阅读技能与左侧OTS和左半球阅读相关区域网络之间连接性的增加呈正相关。另一方面，我们没有观察到左侧OTS的模式与阅读技能之间存在关联。最后，我们发现有证据表明左侧OTS的形态和连接性与其脑沟模式相关。
