Size, mean and peak amplitude, and approximate peak location in standard stereotaxic space and Brodmann area, of activation clusters in multiple regression maps showing group fMRI activity linearly related to SOA in the syllable and chirp tasks versus rest, and in the contrast between the tasks

Peaks listed were at least 30 mm apart. Clusters with negative amplitude values are listed in separate tables and reflect activation stronger in the second relative to first condition in the contrast. For some of the larger clusters, multiple peaks are listed (Talairach and Tournoux, 1988). R, Right; L, left; BA, Brodmann area; a, anterior; C, cingulate; MTG, middle temporal gyrus.
