Accessing orthographic representations from speech: the role of left ventral occipitotemporal cortex in spelling.

Ludersdorfer P, Kronbichler M, Wimmer H - Hum Brain Mapp (2014)

Bottom Line: Such an orthographic word lexicon is posited by cognitive dual-route theories of reading and spelling.In the scanner, participants performed a spelling task in which they had to indicate if a visually presented letter is present in the written form of an auditorily presented word.Our results suggest that activation of left vOT during spelling can be attributed to the retrieval of orthographic whole-word representations and, thus, support the position that the left vOT potentially represents the neuronal equivalent of the cognitive orthographic word lexicon.

Spelling versus control conditions. Brain regions activated by the orthographic, the orthographic-phonological, or the phonological spelling condition relative to their respective control condition. All comparisons are thresholded at P < 0.001, voxelwise, with an additional cluster extent threshold of P < 0.05, FWE corrected.

fig02: Spelling versus control conditions. Brain regions activated by the orthographic, the orthographic-phonological, or the phonological spelling condition relative to their respective control condition. All comparisons are thresholded at P < 0.001, voxelwise, with an additional cluster extent threshold of P < 0.05, FWE corrected.

Mentions: To investigate brain regions engaged by the spelling conditions we contrasted each spelling condition with its respective control condition. Specifically, the orthographic and the orthographic-phonological spelling condition were compared to the word control condition and the phonological spelling condition was compared to the pseudoword control condition. The results of these comparisons are presented in TableIV and Figure 2.
