Brain activity synchronizes with sound waves, even without audible sound, through lip-reading, according to new research published in JNeurosci.
Bourguignon et al. used magnetoencephalography to measure brain activity in healthy adults while they listened to a story or watched a silent video of a woman speaking. The participants’ auditory cortices synchronized with sound waves produced by the woman in the video, even though they could not hear it.
The synchronization resembled that in those who actually did listen to the story, indicating the brain can glean auditory information from the visual information available to them through lip-reading. (1)
