Language depends critically on the integration of lexical information across multiple words to derive semantic concepts. Limitations spatiotemporal resolution have previously rendered it difficult isolate processes involved in integration. We utilized intracranial recordings epilepsy patients (n = 58) who read written word definitions. Descriptions were either referential or non-referential a common object. Semantically sentences enabled high frequency broadband gamma activation (70-150 Hz) inferior frontal sulcus (IFS), medial parietal cortex, orbitofrontal cortex (OFC) and temporal lobe left, language-dominant hemisphere. IFS, OFC posterior middle gyrus activity was modulated by coherence sentences, exposing effects that independent task-based status. Components this network, alongside superior sulcus, engaged for did not clearly reduce search space final word. These results indicate existence complementary cortical mosaics cortex.
