Brain-based help for adults with dyslexia.Intensive phonics phonics Method of reading instruction that breaks language down into its simplest components. Children learn the sounds of individual letters first, then the sounds of letters in combination and in simple words. instruction literally gets into the heads of adults with dyslexia dyslexia (dĭslĕk`sēə), in psychology, a developmental disability in reading or spelling, generally becoming evident in early schooling. To a dyslexic, letters and words may appear reversed, e.g. , according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. a new brain-imaging study. After completing such training, these individuals display modified brain activity that apparently fosters their improved performance on reading tests, concludes a team of neuroscientists led by Guinevere F. Eden of Georgetown University Medical Center Georgetown University Medical Center (GUMC) is the medical campus at Georgetown University. It is co-located with Georgetown University Hospital on the University's main campus in Washington, DC. in Washington, D.C. Dyslexia manifests itself primarily as a severe reading difficulty in people of at least average intelligence. Phonies techniques, which match appropriate sounds to written letters, have boosted reading skills in children with dyslexia but hadn't previously been studied in adults with the condition. Eden and her coworkers recruited 19 adults with good reading skills and 19 adults with dyslexia. A functional magnetic resonance imaging functional magnetic resonance imaging n. Abbr. fMRI Magnetic resonance imaging that provides three-dimensional images of the brain based on changes in blood flow and that can be correlated with brain functions. (fMRI) scanner measured blood flow throughout participants' brains as they listened to spoken words and tried to repeat each of them without its initial sound. For example, the correct response after hearing "cat" was to say "at." A left brain region already implicated im·pli·cate tr.v. im·pli·cat·ed, im·pli·cat·ing, im·pli·cates 1. To involve or connect intimately or incriminatingly: evidence that implicates others in the plot. 2. in decoding alphabetic scripts exhibited particularly low blood flow, suggesting reduced neural activity, in those with dyslexia. Ten of the adults with dyslexia then completed 8 weeks of phonies-based training. The rest received no instruction. When again asked to repeat words minus their initial sounds, the volunteers who had undergone training displayed greater activity in the reading-related part of the left brain than they had before instruction and also boosts in several right brain areas that may contribute to reading, the scientists conclude in the Oct. 28 Neuron. |
