¹Brain regions more activated during speech auditory (only) perception of words compared to still control condition. ²Brain regions more activated during speech visual (lipreading) perception of words compared to still control condition in AV hearing speakers. ³Brain regions activated during AV integration in hearing speakers: [speech AV > (speech A + speech visual)] Ω (speech A > still) Ω (speech visual > still). Activations of speech A-still and speech visual-still are reported at p < 0.05 whole brain corrected. Activations of speech AV integration are uncorrected for multiple comparisons; p < 0.001. AV, audio-visual; A, auditory; LR, lipreading. L, Left; R, Right; BA, Brodmann area; x, y, z are standard stereotaxic coordinates in the MNI (Montreal Neurological Institute) system.
