Brain areas decoding acoustic and visual communication cues

Visual speech through lip movements is a key component of communication, but the brain mechanisms that process these visual and auditory cues are still unclear. Here, a multifactorial whole-brain magnetoencephalography (MEG) classification of volunteers was used to identify brain areas activated during different tests of auditory and visual communication. The results showed which areas processed auditory and visual mediated word identities. However, only two brain areas were identified that were activated along with auditory and visual cues and were clearly separated from other areas that represented sensory-mediated word identity. Overall, the researchers elucidate which brain areas are activated by two different types of communication and suggest that word comprehension may be more specific to communication channels than is currently thought.
