Abstract: According to the "classic" and the "new" model, developmental dyslexia (DD) is associated with dysfunctions of the left temporoparietal (TP), ventral occipitotemporal (vOT) and frontal brain circuits. However, these models make different anatomo-functional predictions about the effects of age and orthographic depth on the neural correlates of DD. To test the influence of age and orthographic depth and their interaction on the neurobiology of reading we meta-analyzed 34 fMRI studies by combining the CluB and the GingerALE methods. Our meta-analytic results challenged both models and allowed us to generate a refined neurocognitive framework called the "Anatomo-functional, Developmental, and Orthographic Depth (ADOD) model of DD". The ADOD model describes the interacting effects of age and orthography on the neurobiology of DD and suggests brand new conceptions on the role of the left TP cortex in reading together with a subtler parcellation of the vOT areas according to a rostro-caudal gradient.
