Figure 3.

Written text contrasted with false font, using the same display design as in Figure 2 and a yellow overlay on the coregistered slices. The response profiles across all five conditions are shown for two peak voxels, identified within SPM99, at either end of the left STS. The size of effect (in arbitrary units) for the conditions used in the contrast, written text (writ; black bar) and false font (ff; white bar), are shown in relation to activity in response to speech (sp), rotated speech (rot), and the number task (nos), shown as gray bars. Mean activity (±SEM) for all five conditions was normalized around zero. Coordinates (in millimeters) show the location of peaks in Montreal Neurological Institute space, located within the posterior STS (1) and anterior STS (2). The dashed outlines draw attention to the equivalent response to rotated speech and written text at the two peak voxels.
