Summary figure of sentence identity coding in the beta phase ΔTPSim and the gamma power ΔTPSim. Black-rimmed circles represent regions that coded sentence identity in the phase of beta oscillations. Small colored crosses represent single electrodes that coded sentence identity in broadband gamma power fluctuations. A, Sentence identity coding during listening (left) and speaking (right). B, Sentence identity coding during WM maintenance with trials time-locked on the stimulus onset (left), on the different stimulus offsets (middle), and on the individual speech onsets (right). Whereas input-related sentence identity coding in the beta band was observed in the auditory association cortices and the IFG, beta phase coding in the motor cortex depended on the perception of the entire sentence. There is an overall paucity of electrodes coding sentence identity in the broadband gamma signal compared with coding in the beta band.
