Grey matter substrates of the imitation of transitive and intransitive MF and ML gestures (results from models with single covariate of interest).Abbreviations: l_PCUN, left precuneus; l_MidOCC, left middle occipital cortex; r_SFC, right superior frontal cortex; r_Mid_CC, right middle cingulum; l_PCC, left posterior cingulum; l_SMA, left supplementary motor area; r_SMA, right supplementary motor area; l_SPC, left superior parietal cortex. Blobs colours: green = transitive ML; red = transitive MF; blue = intransitive ML.
