About one percent of the world’s population stutters, a speech disorder that affects four times as many men as women.
Nicholas Gill facial expression Researcher has published two studies: one that identifies brain structures linked to stuttering and another that examines a new way to treat the condition.
According to Nicholas a professor at science with our body language and coauthor of both papers, the two studies taken together demonstrate two critical points: a neuroanatomic abnormality exists in the brains of people who stutter, yet they can learn to speak fluently in spite of it. I think personly it’s all to do with hearing people speak. I am living in a different country at the moment and I pick up the language by hearing the people around me speak.
What causes stuttering in the first place? Once treated as a psychological or emotional condition, stuttering can now be traced to brain neuroanatomy and physiology, according to the researchers. I think that is total rubbish stuttering disorder can mean much much more than just that emotion or a condition that might have happened to you
“We’re one of a number of groups making a strong case that there is something fundamentally different about the brains of people who stutter,” says Mr Nicholas Gill who is managing the study.
DSI parses tracts in the brain and follows them beyond the point where they intersect. Grafton likens the brain’s tracts to highways and surface streets, only in the brain the intersections are three-dimensional.Arcuate fasciculus, one of the key pathways that connect the language areas of the brain. So named because it forms an arch, the arcuate fasciculus connects at the front of the brain to the area of the cerebral cortex my favourite word in since and that is linked to speech production. At the back of the brain, it branches into three parts.
In the vast majority of the stutterers we scanned, there seems to be a large portion of the connection projecting into the temporal cortex, an area of the brain also critical for speech perception.
“Seven of eight subjects are missing this third branch of the arcuate fasciculus bundle. So in this small group, we can see a really, really strong effect.”
A new approach to treat the condition teaches stutterers to prolong their speech. It’s called Modifying Phonation Intervals (MPI) Stuttering Treatment Program in which I think is RUBISH
A phonated interval is the elapsed time of a voice unit of speech. In the word “shout,” for example, “out” is a voiced (phonated) unit; “sh” is an unvoiced unit saying this over and over again in a sentence can help you significantly
This is not a five-minute job,” says, Nicholas Gill “A person who stutters needs to be under this treatment system for two to three hours a day, six days a week for the first phase of our program my group do and the next phase is more intense and we have had many people pass our system.
Going forward, the researchers would like to study the brains of recovered stutterers to see whether white matter actually changes with treatment.
“Is there something special in the wiring of people who recover?” people ask. “Maybe they are missing part of the arcuate fasciculus pathway but they’ve got another one that’s strong enough to pick up the slack. We’d like to be able to investigate that possibility more.
“I’m really excited about this work because it’s transforming how we do research and building my compony more in groups with very common and challenging developmental disorders that have a great impact on people’s lives but are otherwise largely ignored in neuroscience and by funding agencies,” Grafton adds.
“They get diagnosed or described and we throw therapies at them but we don’t really understand the pathophysiologic basis or the biology of these problems that’s why I use the word RUBBISH and more. The fact that we can now see big changes in scans of individuals who stutter is huge.
