Reading within and beyond the classical reading network: Contributions of the ventral occipitotemporal cortex and thalamic nuclei to reading processes

Reading is classically thought to be supported by a left-lateralized cortical brain network. Within this network, the ventral occipitotemporal cortex (vOTC) is key region for recognizing visual patterns, and a subset of this circuitry can be trained to rapidly identify word forms. Although the thalamus is typically found activated in neuroimaging reading studies with typical and atypical populations, the potential role of different thalamic nuclei in reading processes have been widely unexplored. In this talk, I will present a refined characterization of vOTC reading circuitry using a multimodal Magnetic Resonance Imaging (MRI) approach combining functional, structural, quantitative MRI and behavioral data and revealing two distinct word-responsive vOTC areas differentially implicated in visual feature extraction and integrating information with other regions of the language network. Furthermore, I will present a model and preliminary data regarding the involvement of different thalamic nuclei in typical and atypical reading. These findings advance our understanding linking function and structure and revealing the pathways of distinct reading-related processes.
