Activation maps for the comparison between mental and motor verbs.

Graphical representation of GLM’s results, brain regions activated in the contrast mental > motor verbs in red, same contrast when the effect of visual processing (i.e., symbols) is removed, in green, and when the effect of phonological processing (i.e., pseudo-verbs) is removed, in blue. Coordinate z of multislices in cerebellum: a = : a = -24, b = -29, c = -34, and d = -39. Color bars show z scores. LH: left hemisphere; RH: right hemisphere.</p

PPI results for motor, mental and pseudo verbs with respect to symbols.

Graphical representation of PPI results with seeds in L-LOC, L-MTG, L-SMA, and R-cerebellum, brain regions functionally connected in the contrast motor > symbols in red, mental > symbols in green, and pseudo-verbs > symbols in blue. Color bars show z scores. LH: left hemisphere; RH: right hemisphere.</p

Brain areas exhibiting significant connectivity during motor > pseudo verbs and mental > pseudo verbs, according to PPI analysis with seeds in L-LOC, L-SMA and R cerebellum.

The x, y, and z coordinates are in MNI space, regions were labelled according to Harvard-Oxford Cortical and Subcortical Atlases in FSLVIEW. L = Left region or hemisphere. R = Right region or hemisphere. (PDF)</p

PPI results for the comparison between mental and motor verbs.

Graphical representation of PPI results with the R-cerebellum seed, brain regions functionally connected in the contrast mental > motor green. Color bar shows z scores. Coordinate z slice in cerebellum = -29. LH: left hemisphere; RH: right hemisphere.</p

Activation maps for the comparison between verbs and pseudo-verbs.

Graphical representation of GLM’s results, brain regions activated in the contrast verbs > pseudo-verbs in red, and pseudo-verbs > verbs in aqua. Coordinate z of multislices in cerebellum:: a = -24, b = -29, c = -34, and d = -39. Color bars show z scores. LH: left hemisphere; RH: right hemisphere.</p

Brain areas exhibiting significant activation in whole brain analysis during verbs > pseudo verbs and pseudo-verbs > verbs contrasts according to GLM analysis.
