Typical and group averaged activation of the cerebrum and cerebellum.(A) Single subject activation data from a representative Broca Left subject, overlaid on left and right cerebral surfaces rendered in the subject's native space (FreeSurfer); at far right, the same single subject's cerebellar activation rendered, after alignment with the spatially unbiased infratentorial template (SUIT) (Z > 2.3, p = 0.01). (B) Single subject activation data from a typical Broca Right subject, with cerebral and cerebellar rendering as in (A). (C) Single Broca Non-lateralized subject data, with cerebral and cerebellar rendering as in (A). (D) Group averaged activation data from all Broca Left subjects overlaid on FreeSurfer average subject surfaces, with cerebellar data rendered on SUIT. (E) Group averaged activation data from all Broca Right subjects. For group cerebellum activations, the Broca Left group is shown with 3 levels of threshold: p = 0.01, p = 0.001, and p = 0.00001. For the Broca Right group, activation is shown only at threshold p = 0.01.
