A study uncovers the part of the brain in-charge of speech processing.
An research group of New York said that the inquiry on whether the mind has a particular part that just controls speech is at long last answered following a long study. Specialists found out that it is superior temporal sulcus which is situated the brain’s temporal lobe.
“We now know there is at least one part of the brain that specializes in the processing of speech and doesn’t have a role in handling other sounds,” David Poeppel a study senior author, a professor in the department of Psychology and Center for Neural Science, announced in a university news release.
Together with his partners, studies were done on the volunteers as their brains were subjected to a scanning device while listening to a variety of sounds that include woofing pooches, pingpong to firecrackers. With a specific end goal to see whether the members were responding to other sounds and not to a usual dialect that they know of, the scientists let them listen to a German speech that they didn’t understand.
The outcome was that the majority of the sounds appeared to bring about action in the fleeting flap’s sound-related cortex but the discourse sounds brought on a movement in the superior temporal sulcus as it responded to the sound. This convinced the specialists to a conclusion that the transient is in charge of the preparing of discourse.
What it didn’t discuss is what the relation with the brain center to the inability of the autistic people to learn how to speak. Is there something wrong with their brain’s speech processing center?
The study turned out on May 8 at the Journal Nature Neuroscience.
