A: Topographical distribution of cortical activation (left-hemispheric view) in the source space (Minimum Norm Estimates, MNE, in nanoAmperemeter, nAm) for verbs presented in isolation, averaged across subjects. MNE were projected onto a standard brain following [28, 29]. In the time window 250–300 ms (left graph) after stimulus onset, most prominent activation occurred in temporal areas; activation in the frontal areas was weaker and later (350–450 ms, right graph). B: Time course of activation for verbs presented in isolation averaged across subjects separately for the three verb categories (with one, two and three arguments) in the left temporal area. C: Group mean and standard error of activity (ordinate: MNE amplitude in nAm) for isolated verbs (abscissa: verbs with either one, two or three arguments) at 250–300 ms.
