In conclusion, our data show that phase and power encoding are independent and are processed by largely non-overlapping neural populations within the STG (7/7).

Lastly, when comparing cong vs incong conditions, we found the different mouth movement produced only a small difference in theta phase in the anterior STG, indicating a limited role of visual speech in ongoing auditory entrainment (6/7)

to test if ITPC and power effects are present at the same electrodes within a participant,we ran a correlation between the cond diffs in each measure at the elec lvl. Phase & power effects are generally unrelated, only 1 of 21 sub showed a sig. corr. btn the two measures (5/7)

If these pre- and post-auditory-onset effects are independent, we would expect to see a significant interaction between condition (congruent-audiovisual vs auditory-alone) and measure (ITPC vs Power). We did find significant interactions across the STG. (4/7)

Comparing cong-av and auditory-alone conditions, we replicated prior findings and showed that pre-speech onset, preparatory mouth movement led to theta phase reset across the STG, meanwhile post-speech onset, mouth movements modulates only in posterior STG. (3/7)

we recorded iEEG when auditory-alone, cong-audiovisual and incong-audiovisual word stimuli were presented to subjects. The incong videos had different mouth evolutions but were designed to give same auditory onset predictions. (2/7)
