发育性阅读障碍是一种常见的神经发育障碍，与语音的行为和神经处理改变有关，但这种联系的范围和性质尚不确定。有人提出，更多的可变听觉处理可能是这种疾病的一些核心缺陷的基础。在目前的研究中，脑磁图(MEG)数据是从患有和没有阅读障碍的成年人那里获得的，同时他们被动地听或主动地分类来自/ba/-/da/辅音连续体的记号。在我们的两个行为评估中，我们都没有观察到两个组在对这一连续体的积极范畴知觉上的显著差异。在被动听的过程中，阅读困难的成年人在与听觉、语言和阅读相关的六个大脑皮层区域表现出与典型阅读成年人一样一致的神经反应。然而，他们在左侧边缘上回表现出的一致性明显较低，在阅读障碍组中，一致性越大，解码技能越差。只有当神经数据以高时间分辨率入库时，左侧边缘上回的组差异才明显，并且只有在被动状态下才显着。有趣的是，与被动倾听相比，在主动归类过程中，两组受试者的一致性都显著提高。这些发现表明，患有阅读障碍的成年人在对语音的反应中表现出典型的神经一致性水平，但左侧缘上回除外，而且在两组人对语音的主动感知和被动感知过程中，这种一致性增强。
Developmental dyslexia is a common neurodevelopmental disorder that is associated with alterations in the behavioral and neural processing of speech sounds, but the scope and nature of that association is uncertain. It has been proposed that more variable auditory processing could underlie some of the core deficits in this disorder. In the current study, magnetoencephalography (MEG) data were acquired from adults with and without dyslexia while they passively listened to or actively categorized tokens from a /ba/-/da/ consonant continuum. We observed no significant group difference in active categorical perception of this continuum in either of our two behavioral assessments. During passive listening, adults with dyslexia exhibited neural responses that were as consistent as those of typically-reading adults in six cortical regions associated with auditory perception, language, and reading. However, they exhibited significantly less consistency in the left supramarginal gyrus, where greater inconsistency correlated significantly with worse decoding skills in the group with dyslexia. The group difference in the left supramarginal gyrus was evident only when neural data were binned with a high temporal resolution and was only significant during the passive condition. Interestingly, consistency significantly improved in both groups during active categorization versus passive listening. These findings suggest that adults with dyslexia exhibit typical levels of neural consistency in response to speech sounds with the exception of the left supramarginal gyrus, and that this consistency increases during active versus passive perception of speech sounds similarly in the two groups.
