Georgetown University Medical Center|Georgetown University
central question study neural basis written language whether reading spelling utilize shared orthographic representations recent studies employing fmri test question report left inferior frontal gyrus ifg ventral occipitotemporal cortex votc active spelling reading subjects purcell et al 2011a rapp lipka 2011 spatial resolution fmri limits interpretation findings specifically unknown neurons encode orthography reading also involved spelling words address question employing eventrelated functional magnetic resonance imagingadaptation fmria paradigm designed examine shared orthographic representations across spelling reading first identified areas independently showed adaptation reading adaptation spelling identified spatial convergence two separate maps via conjunction analysis consistent previous studies purcell et al 2011a rapp lipka 2011 analysis revealed left dorsal ifg votc supplementary motor area validate observations interrogated regions using acrosstask adaptation technique found adaptation across reading spelling left dorsal ifg ba 449 final analysis focused specifically visual word form area vwfa votc whose variability location among subjects requires use subjectspecific identification mechanisms glezer riesenhuber 2013 using functional localizer reading defined vwfa subject found adaptation effects within spelling reading conditions respectively well across spelling reading none effects observed phonologicalsemantic control condition conclude left dorsal ifg vwfa involved accessing orthographyspecific representations spelling reading
