This peak is located in white matter in the group map. When explored on subject-by-subject basis in native space, this activation sourced from the superior frontal sulcus in 8 out of 17 subjects.
In order to provide a comparison for localization purposes of the visual word form area of the fusiform gyrus, the contrast (Letter + Prompt vs. Rest) was used. Coordinates of the strongest activation in this general region from this reference contrast are x = −36, y = −48, z = −14, t = 8.47, p = 2.6 × 10−7.
