Representational interactions during audiovisual speech entrainment: Redundancy in left posterior superior temporal gyrus and synergy in left motor cortex
Fig 4
Redundancy and synergy in congruence effect.
Comparison between conditions of matching versus nonmatching audiovisual speech signals in “AV congruent” condition entails both attention and congruence effects. To separate this effect, we additionally analyzed contrast for congruence (“AV congruent” > “All incongruent”) first. (A) Redundancy for congruence effect is observed in left inferior frontal region and pSTG/S and right posterior middle temporal cortex (Z-difference map at P < 0.005). (B) Synergistic information for congruence effect is found in superior part of somatosensory and parietal cortices in left hemisphere (Z-difference map at P < 0.005). The underlying data for this figure are available from the Open Science Framework (https://osf.io/hpcj8/). pSTG/S, posterior superior temporal gyrus/sulcus.
