Lesion characteristics for agrammatic participants

Participant Lesion localization
1 Pars triangularis and pars orbitalis of the IFG and prefrontal cortex,
extending to the primary somatosensory cortex, and including anterior
MTG and STG
3 Supramarginal and angular gyri extending to the fusiform gyrus, as well
as pars operacularis of the IFG and the premotor cortex
4 Pars triangularis and pars orbitalis of the IFG, dorsolateral prefrontal
cortex, pre- and postcentral gyurs, and extending to the rostral part of the
MTG and STG
5 Pars orbitalis and pars opercularis of the IFG, anterior MTG and STG,
extending to subcortical regions
6 Pars opercularis, premotor cortex, inferior precentral and postcentral
gyri, extending to the anterior temporal lobe
7 Frontal, temporal, and parietal regions
8 Posterior lesion, including portions of the inferior, middle and superior
temporal gyri, and pars opercularis
9 Inferior frontal and prefrontal gyri, extending to the anterior MTG and
STG
11 Massive infarction involving the entire distribution of the left anterior
and middle cerebral arteries; some sparing of posterior temporal lobe
12 Posterior regions, in particular the STG, supramarignal gyrus, and
superior parietal lobule, and encompassing a small portion of tissue in
the IFG
13 Pars orbitalis of the IFG, STG and MTG, extending to the fusiform gyrus

Note: IFG = inferior frontal gyrus; MTG = middle temporal gyrus; STG = superior temporal gyrus
