Localization and Functional Characterization of an Occipital Visual Word form Sensitive Area

Abstract In human occipitotemporal cortex, category-specific processing for visual objects seems to involve pairs of cortical regions, often with one located in the occipital cortex and another more anteriorly. We investigated whether such an arrangement might be the case for visual word processing....
