EDINBURGH, Scotland (UPI) -- Scottish researchers say they found right
hemisphere differences in the brains of those with dyslexia.
The study, published in BMC Neuroscience, used magnetic resonance
imaging to look at the brains of both dyslexic and normal readers and
then linked neurological differences to different language
difficulties within the dyslexic group.
Cyril Pernet of the University of Edinburgh led a team of researchers
that created a "typical brain" by combining the scans of 39 normal
readers. All 38 of the brain scans of people with dyslexia revealed
differences in two parts of the brain on the right side. These
differences were then associated with language test performance.
"These results provide evidence for the existence of various subtypes
of dyslexia characterized by different brain phenotypes," Pernet said
in a statement.
"In addition, behavioral analyses suggest that these brain phenotypes
relate to different deficits of automatization of language-based
processes."
