Turkish whistling makes asymmetries in the brain disappear

Left hemisphere not dominant in the perception of all languages


2015-08-17
(Press-News.org) Researchers at the Ruhr-Universität Bochum have debunked the theory that the left brain hemisphere is dominant in the processing of all languages. To date, it has been assumed that that dominance is not determined by the physical structure of a given language. However, the biopsychologists have demonstrated that both hemispheres are equally involved in the perception of whistled Turkish. Onur Güntürkün, Monika Güntürkün and Constanze Hahn report in the journal "Current Biology".

Common theory: left hemisphere dominant in language perception

The perception of all spoken languages - including those with clicks -, written texts and even sign language involves the left brain hemisphere more strongly than the right one. The right hemisphere, on the other hand, processes acoustic information via slow frequencies, pitch and melody. According to the currently commonly held opinion, the asymmetry in language processing is not determined by the physical properties of a given language. "The theory can be easily verified by analysing a language which possesses the full range of physical properties in the perception of which the right brain hemisphere is specialised," says Onur Güntürkün. "We can count ourselves lucky that such a language exists - namely whistled Turkish."

Hearing test with spoken and whistled Turkish

The Bochum team tested 31 inhabitants of Ku?köy, a village in Turkey, who speak Turkish and whistle it as well. Via headphones, they were presented either whistled or spoken Turkish syllables. In some test runs, they heard different syllables in both ears, in other runs the same syllables. They were asked to state which syllable they had perceived. The left brain hemisphere processes information from the right ear, the right hemisphere from the left ear. For spoken Turkish, a clear asymmetry emerged: If the participants heard different syllables, they perceived the syllables from the right ear much more frequently - a dominance of the left brain hemisphere. That asymmetry did not exist in whistled Turkish. "The results have shown that brain asymmetries occur at a very early signal processing stage," concludes the researcher from Bochum.

Turkish researcher discovers whistled Turkish in Australia

Whistled Turkish contains the same vocabulary and follows the same grammatical rules as Turkish. "It is simply a different format, in the same way as written and spoken Turkish are," describes Onur Güntürkün. A small group of people in the mountainous north-eastern part of Turkey use whistled language which can be heard over distances of several kilometres. "Even though I am Turkish, I had, strangely enough, never heard of whistled Turkish. I encountered it in Australia for the first time, when a colleague told me about it," explains the biopsychologist. "I knew instantly that nature had thus provided the perfect method for verifying the theory regarding asymmetry of language perception."

Protective eyewear reduces field hockey eye injuries without increased concussion risk

2015-08-17
PROVIDENCE, R.I. - A study conducted by researchers at Hasbro Children's Hospital, Boston Children's Hospital, Fairfax (VA) County Public Schools and the University of Colorado School of Medicine has found that nationally mandated protective eyewear results in a greater than three-fold reduced risk of eye and orbital injuries in high school (HS) girls' field hockey players without increasing rates of concussion. Each academic year, more than 64,000 girls participate in HS-sanctioned field hockey in the United States. Head, facial, and eye injuries are common among field ...

Whistled Turkish challenges notions about language and the brain

Whistled Turkish challenges notions about language and the brain
2015-08-17
Generally speaking, language processing is a job for the brain's left hemisphere. That's true whether that language is spoken, written, or signed. But researchers reporting in the Cell Press journal Current Biology on August 17 have discovered an exception to this rule in a most remarkable form: whistled Turkish. "We are unbelievably lucky that such a language indeed exists," says Onur Güntürkün of Ruhr-University Bochum in Germany. "It is a true experiment of nature." Whistled Turkish is exactly what it sounds like: Turkish that has been adapted into ...

Health care must be key issue in Canada's federal election

2015-08-17
Health care is a major responsibility of Canada's federal government and must be a key issue in the fall election, argues Dr. Matthew Stanbrook in an editorial in CMAJ (Canadian Medical Association Journal). "The federal government seems to be trying to get itself out of the health care business," states Dr. Stanbrook, deputy editor, CMAJ. "It cannot. Many essential aspects of health care are a federal responsibility, and our biggest, most complex problems in the health care system cannot be solved without federal leadership." He argues that over most of the last 10 ...

2015-08-17
Nearly 2 million people throughout the Great Plains and California above aquifer sites contaminated with natural uranium that is mobilized by human-contributed nitrate, according to a study from the University of Nebraska-Lincoln. Data from roughly 275,000 groundwater samples in the High Plains and Central Valley aquifers show that many Americans live less than two-thirds of a mile from wells that often far exceed the uranium guideline set by the Environmental Protection Agency. The study reports that 78 percent of the uranium-contaminated sites were linked to the ...

Peripherally inserted central catheters can cause blood clots in lower limbs

2015-08-17
Philadelphia, PA, August 17, 2015 -- Peripherally inserted central catheters (PICCs), a type of IV typically inserted in a vein in the arm, are frequently used by healthcare professionals to obtain long-term central venous access in hospitalized patients. While there are numerous benefits associated with PICCs, a potential complication is deep vein thrombosis (DVT), or blood clots, in upper limbs. A new study of more than 70,000 patients in 48 Michigan hospitals indicates that PICC use is associated not only with upper-extremity DVT, but also with lower-extremity DVT. The ...

Discovery of a salamander in amber sheds light on evolution of Caribbean islands

Discovery of a salamander in amber sheds light on evolution of Caribbean islands
2015-08-17
CORVALLIS, Ore. - More than 20 million years ago, a short struggle took place in what is now the Dominican Republic, resulting in one animal getting its leg bitten off by a predator just before it escaped. But in the confusion, it fell into a gooey resin deposit, to be fossilized and entombed forever in amber. The fossil record of that event has revealed something not known before - that salamanders once lived on an island in the Caribbean Sea. Today, they are nowhere to be found in the entire Caribbean area. The never-before-seen and now extinct species of salamander, ...

Women's health, education, marital status pre-pregnancy affect birth weight of girls

2015-08-17
Irvine, Calif., August 17, 2015 - A woman's weight at birth, education level and marital status pre-pregnancy can have repercussions for two generations, putting her children and grandchildren at higher risk of low birth weight, according to a new study by Jennifer B. Kane, assistant professor of sociology at the University of California, Irvine. The findings are the first to tie social and biological factors together using population data in determining causes for low birth weight. "We know that low-birth-weight babies are more susceptible to later physical and cognitive ...

The device dramatically expands the scope of research that can be carried out through optogenetics to include experiments involving mice in enclosed spaces or interacting freely with other animals. The work is published in the Aug. 17 edition of Nature Methods. "This is a new way of delivering wireless power for optogenetics," said ...

In first year, 2 Florida laws reduce amount of opioids prescribed, study suggests

2015-08-17
Two Florida laws, enacted to combat prescription drug abuse and misuse in that state, led to a small but significant decrease in the amount of opioids prescribed the first year the laws were in place, a new study by Johns Hopkins Bloomberg School of Public Health researchers suggests. One measure created a Prescription Drug Monitoring Program, a database that tracks individual prescriptions, including patient names, dates and amounts prescribed, so physicians can be on the lookout for excesses associated with addiction and illicit use. Another addresses so-called "pill ...

Children of military parents, caregivers at greater risk for adverse outcomes

2015-08-17
Children with parents or caregivers currently serving in the military had a higher prevalence of substance use, violence, harassment and weapon-carrying than their nonmilitary peers in a study of California school children, according to an article published online by JAMA Pediatrics. While most young people whose families are connected to the military demonstrate resilience, war-related stressors, including separation from parents because of deployment, frequent relocation and the worry about future deployments, can contribute to struggles for some of them, according ...
