Abstract
Event-related fMRI was used to test the hypothesis that the visual
word form area in the left fusiform gyrus holds a modality-specific
and prelexical representation of visual words. Subjects were engaged
in a repetition-detection task on pairs of words or pronounceable
pseudo-words that could be written or spoken. The visual word form
area responded only to written stimuli, not to spoken stimuli, independently
of their semantic content. We propose that the occasional activation
of the fusiform gyrus when listening to spoken words is due to the
topdown recruitment of visual orthographic or object representations.
