Scientists Are Researching The Causes Of The Inability To Read.
Glitches in the connections between unfailing acumen areas may be at the root of the common learning hubbub dyslexia, a new study suggests. It's estimated that up to 15 percent of the US citizens has dyslexia, which impairs people's ability to read. While it has long been considered a brain-based disorder, scientists have not conceded exactly what the issue is.

The new findings, reported in the Dec 6, 2013 circulation of Science, suggest the blame lies in faulty connections between the brain's storage spell for speech sounds and the brain regions that process language. The results were surprising, said be conducive to researcher Bart Boets, because his team expected to find a different problem. For more than 40 years many scientists have meditation that dyslexia involves defects in the brain's "phonetic representations" - which refers to how the central sounds of your native language are categorized in the brain.

But using sensitive perception 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 regular reading skills. Instead, it seemed that in citizenry with dyslexia, language-processing areas of the brain had difficulty accessing those phonetic representations. "A apt metaphor might be the comparison with a computer network," said Boets, of the Leuven Autism Research Consortium in Belgium.

And "We show that the data - the data - on the server itself is intact, but the correlation to access this information is too slow or degraded". And what does that all mean? It's too soon to tell, said Boets. First of all this studio used one form of brain imaging to study a small conglomeration of adult university students. But dyslexia normally begins in childhood.

Brain Scans Can Reveal The Occurrence Of Autism

Brain Scans Can Reveal The Occurrence Of Autism.
A group of wisdom imaging that measures the circuitry of brain connections may someday be used to recognize autism, new research suggests. Researchers at McLean Hospital in Boston and the University of Utah employed MRIs to analyze the microscopic fiber structures that make up the brain circuitry in 30 males old 8 to 26 with high-functioning autism and 30 males without autism. Males with autism showed differences in the chalky matter circuitry in two regions of the brain's temporal lobe: the supervisor temporal gyrus and the temporal stem. Those areas are involved with language, feeling and social skills, according to the researchers.

Based on the deviations in brain circuitry, researchers could distinguish with 94 percent Loosely precision those who had autism and those who didn't. Currently, there is no biological test for autism. Instead, diagnosis is done through a long-drawn examination involving questions about the child's behavior, language and social functioning. The MRI investigation could change that, though the study authors cautioned that the results are preliminary and need to be confirmed with larger numbers of patients.

So "Our swat pinpoints disruptions in the circuitry in a brain division that has been known for a long time to be responsible for language, social and emotional functioning, which are the major deficits in autism," said leadership author Nicholas Lange, director of the Neurostatistics Laboratory at McLean Hospital and an colleague professor of psychiatry at Harvard Medical School. "If we can get to the physical infrastructure of the potential sources of those deficits, we can better understand how exactly it's happening and what we can do to develop more effective treatments". The bone up is published in the Dec 2, 2010 online edition of Autism Research.
