Indoor Tanning Salons Lie About Health Risks: Investigation
Most indoor tanning salons do not tell Gucci outlet, gucci bags, cheap gucci shoes 2012 sale customers the truth about potential health risks, says a U.S. House Energy and Commerce Committee investigative report.
Posing as fair-skinned 16-year-old girls, investigators contacted 300 indoor tanning salons across the nation. Ninety percent of the salons told the callers that indoor tanning did not pose health risks, ABC News reported.
More than half of the salons denied that indoor tanning increased the risk of skin cancer and more than three-quarters said indoor tanning actually benefits the health of teen girls.This ability to decode electrical activity in an area of the auditory system called the superior temporal gyrus may one day enable neuroscientists to hear the imagined speech of stroke or other patients who can't speak, or to eavesdrop on the constant, internal monologues that run through people's minds, the researchers explained in a journal news release.
"This is huge for patients who have damage to their speech mechanisms because of a stroke or Lou Gehrig's disease [amyotrophic lateral sclerosis] and can't speak," Robert Knight, a professor of psychology and neuroscience, www.discount-sell.com said in the news release. "If you could eventually reconstruct imagined conversations from brain activity, thousands of people could benefit."
However, the study's first author, post-doctoral researcher Brian Pasley, noted that "this research is based on sounds a person actually hears, but to use this for a prosthetic device, these principles would have to apply to someone who is imagining speech."
He explained that "there is some evidence that perception and imagery may be pretty similar in the brain. If you can understand the relationship well enough between the brain recordings and sound, you could either synthesize the actual sound a person is thinking, or just write out the words with a type of interface device."
For the study, Pasley's team tested two different computational models that were designed to match spoken sounds to the pattern of activity in the electrodes when a patient heard a single word. The better of the two models reproduced a sound that was close enough to the original word so that the researchers could correctly guess the word.
The aim of the research was to reveal how the human brain encodes speech, and to then pinpoint the aspects of speech that are necessary for understanding.
"At some point, the brain has to extract away all that auditory information and just map it onto a word, since we can understand speech and words regardless of how they sound," Pasley said.Welcome to gucci outlet shop, all gucci bags and gucci shoes 2012 new arrivals are on cheap sale.
