Lipreading a naturalistic narrative in a female population: Neural characteristics shared with listening and reading

摘要: Introduction Few of us are skilled lipreaders while most struggle with the task. Neural substrates that enable comprehension of connected natural speech via lipreading are not yet well understood. Methods We used a data‐driven approach to identify brain areas underlying the lipreading of an 8‐min narrative with participants whose lipreading skills varied extensively (range 6–100%, mean = 50.7%). The participants also listened to and read the same narrative. The similarity between individual participants’ brain activity during the whole narrative, within and between conditions, was estimated by a voxel‐wise comparison of the Blood Oxygenation Level Dependent (BOLD) signal time courses. Results Inter‐subject correlation (ISC) of the time courses revealed that lipreading, listening to, and reading the narrative were largely supported by the same brain areas in the temporal, parietal and frontal cortices …
