ERP correlates of orthographic typicality and lexicality in written
Running title: ERP effects of typicality and lexicality Abstract Using a speeded lexical decision task, event-related potentials (ERP) and minimum norm current source estimates, we investigated early spatio-temporal aspects of cortical activation elicited by words and pseudowords that varied in their orthographic typicality, i.e. in the frequency of their component letter pairs (bigrams) and tr...
متن کاملTaxi vs. Taksi: On Orthographic Word Recognition in the Left Ventral Occipitotemporal Cortex
The importance of the left occipitotemporal cortex for visual word processing is highlighted by numerous functional neuroimaging studies, but the precise function of the visual word form area (VWFA) in this brain region is still under debate. The present functional magnetic resonance imaging study varied orthographic familiarity independent from phonological-semantic familiarity by presenting o...
متن کاملDyslexic children lack word selectivity gradients in occipito-temporal and inferior frontal cortex
fMRI studies using a region-of-interest approach have revealed that the ventral portion of the left occipito-temporal cortex, which is specialized for orthographic processing of visually presented words (and includes the so-called "visual word form area", VWFA), is characterized by a posterior-to-anterior gradient of increasing selectivity for words in typically reading adults, adolescents, and...
متن کاملReading without the left ventral occipito-temporal cortex
The left ventral occipito-temporal cortex (LvOT) is thought to be essential for the rapid parallel letter processing that is required for skilled reading. Here we investigate whether rapid written word identification in skilled readers can be supported by neural pathways that do not involve LvOT. Hypotheses were derived from a stroke patient who acquired dyslexia following extensive LvOT damage...
متن کاملSensitivity to orthographic familiarity in the occipito-temporal region
The involvement of the left hemisphere occipito-temporal (OT) junction in reading has been established, yet there is current controversy over the region's specificity for reading and the nature of its role in the reading process. Recent neuroimaging findings suggest that the region is sensitive to orthographic familiarity [Kronbichler, M., Bergmann, J., Hutzler, F., Staffen, W., Mair, A., Ladur...
