Structural images of the left hemisphere lesions for participants (A) GOE and (B) AMC. Participant AMC had a titanium mesh plate inserted into his left temporalis muscle following his stroke. The metal inserted into AMC's skull interfered with the MRI scan of that left region and, therefore, it is difficult to pinpoint the exact location of his lesion on the image.

Participant GOE was 65 years old and 18 months post left fronto-temporal stroke (see Figure 1 for structural image). AMC was 49 years old and 20 months post left fronto-temporal stroke (see Figure 1). AMC had a titanium mesh plate inserted in his temporal region following the stroke.
The sequence of displays for (A) the automatic speech task, and (B) naming/reading task that GOE and AMC were asked to complete in the scanner. (A) represents a trial in which the participant had to count from 1 to 21 in the right order, whereas (B) represents a block of trials in which the participant had to name pictures in a series. +, Fixation.

When completing this task (see Figure 2A), participants saw a category label appear on the screen for 3 s (e.g., NUMBERS) followed by three examples of the category sequence (e.g., 1, 2, 3) that appeared for 1.5 s each. When completing this task (see Figure 2B), participants saw an instruction label appear on the screen for 3 s (e.g.,
