Abstract

This study used functional magnetic resonance imaging (fMRI) to investigate the neural substrate underlying the processing of single words, comparingactivation patterns across subjects and within individuals. In a word repetition task, subjects repeated single words aloud with instructions not to move their jaws, In a control condition involving reverse speech, subjects heard a digitally reversed speech token and said aloud the word "crime. " The averaged FMRI results showed activation in the left posterior temporal and inferior frontal regions and in the supplementary motor area, similar to previous PET studies. However, the individual subject data revealed variability in the location of the temporal and frontal activation. Although theseresults support previous imaging studies, demonstrating an averaged localization of auditory word processing in the posterior superior temporal gyrus(STG), they are more consistent with traditional neuropsychological data, which suggest both a typical posterior STG localization and substantial individual variability. By using careful head restraint and movement analysis and correction methods, the present study further demonstrates the feasibility of using overt articulation in fMRI experiments, (C) 2001 Academic Press.
