Figures

On the top half, statistical mapping of the lesioned areas in AHP.

(a) right hemisphere (b) striatum (c) insula (d) axial sections. Pal: pallidum; Put: putamen; ALg: anterior long gyrus; PSg: posterior short gyrus; MSg: middle short gyrus; Tp: temporal pole. On the bottom half, statistical mapping of the brain disconnections in AHP. (e) right hemisphere lateral view; (f) right hemisphere medial view; (g) axial sections. TPJ: temporo-parietal junction; VPF: ventral prefrontal cortex; preSMA: pre-supplementary area; H: hippocampus; Cing: cingulum; SLF III: third (ventral) branch of the superior longitudinal fasciculus; PreSMA: pre-supplementary motor area.

Motor awareness network.

(a) right hemisphere medial view (left) right hemisphere lateral view (right); (b-c) Bayes Factors for all models, each one representing the hypothesis that the damage to grey matter structure and/or the tract disconnection is necessary to explain AHP, against the clinical/demographic model. Ins: insula; TP: temporal pole; Put: putamen; FST: fronto-striatal tract; Cing: cingulum; FAT: frontal aslant tract; SLF III: third branch of the superior longitudinal fasciculus.
