Grey matter reduction in the occipitotemporal cortex in Spanish children with dyslexia: A voxel-based morphometry study

In this study, we used voxel-based morphometry (VBM) to investigate brain differences in grey matter volume associated with a transparent language in a sample of 25 native Spanish participants (13 dyslexic and 12 non-dyslexic children). Results revealed a volume reduction in the left occipitotemporal cortex and right cerebellum in dyslexics. Significantly, the reduction in occipitotemporal areas has been previously linked to reading in transparent languages. Our results support previous studies and are consistent with the idea that reading problems in languages with a shallow orthography are related to the ventral reading network.
