The neural representations for compositional processing have so far been mostly studied during sentence comprehension. In an fMRI study of production, we investigated the brain speaking. We used a rapid serial visual presentation recall paradigm to elicit production from conceptual memory event. With voxel-wise encoding models, probed specificity structure built each sentence, comparing unstructured model word meaning without relational information with that encodes abstract thematic relations and event-specific structure. Whole-brain analyses revealed at different levels was encoded in large left frontal-parietal-temporal network. A comparison semantic structures composed comprehension same sentences showed similarly distributed activity patterns. An ROI analysis over fronto-temporal language parcels above word-specific inferior frontal gyrus. Overall, found evidence network
