Scientists Are Researching The Causes Of The Inability To Read – Part 1 of 3
Scientists Are Researching The Causes Of The Inability To Read. Glitches in the connections between specific brain areas may be at the root of the common learning confusion dyslexia, a new study suggests. It’s estimated that up to 15 percent of the US population has dyslexia, which impairs people’s ability to read. While it has long been considered a brain-based disorder, scientists have not agreed exactly what the issue is.
The new findings, reported in the Dec 6, 2013 issue of Science, suggest the blame lies in faulty connections between the brain’s storage elbow-room for speech sounds and the brain regions that process language. The results were surprising, said lead researcher Bart Boets, because his team expected to find a different problem. For more than 40 years many scientists have concern that dyslexia involves defects in the brain’s “phonetic representations” – which refers to how the basic sounds of your native language are categorized in the brain.
But using sensitive wisdom imaging techniques, Boets and colleagues found that was not the case in 23 dyslexic adults they studied. The phonetic representations in their brains were just as “intact” as those of 22 adults with normal reading skills. Instead, it seemed that in rank and file with dyslexia, language-processing areas of the brain had difficulty accessing those phonetic representations. “A relevant metaphor might be the comparison with a computer network,” said Boets, of the Leuven Autism Research Consortium in Belgium.
