FIGURE 4.

Capturing of the rhythmic phrasal pattern of speech in dPCC. (a) Weights of the linear regression predicting HFB responses based on speech phrasal groupings (ON/OFF speech binary vector). Only speech fragments were used, therefore OFF segments relate to pauses within the continuous stream of speech. (b) Example time courses for a speech fragment showing the rhythmic phrasal pattern in speech (ON/OFF speech binary vector), spectral envelope of the fragment and HFB responses in dPCC in S1 (E69) and S2 (E101). The weight of the linear fit using speech phrasal groupings is also reported per example electrode (β)
