Eyes can work as partial ears: Study

The brain synchronises with inaudible sound waves through lip-reading, states a recently published research.

People have little idea about how listening to any speech can activate the auditory cortex and also synchronise with the rhythmic income of sound waves. It, however, has been evident that lip-reading is helpful in comprehending unintelligible speech.

Bourguignon, et al, is used magnetoencephalography for measuring the brain's activity of any healthy adult while he or she listens to a story or watches a muted video speech.

The participants' auditory cortices synchronise with the sound waves exerted from the video, though there was no audible sound available.

This coordination or synchronisation resembled the similar hearing pattern of those who actually heard the story drawing a conclusion that the brain has the capability to perceive information from visual content through lip-reading.

Researchers believe that this ability arises from the synchronisation of the visual cortex with lip movement. This signal is sent to the other area of the brain that helps in the translation of the movement information into sound information, thus aggravating the understanding ability.
