On Thursday nights near the Brooklyn, N.Y., waterfront, an old firehouse turns into a schoolhouse, where the drills are in Chinese. About a dozen firefighters, EMTs and paramedics are taking the first Mandarin classes, funded by the New York City Fire Department Foundation. New York City boasts the largest Chinese population of any city outside of China, therefore "first responders" want to communicate with more of the New Yorkers they serve. The founder of the language program also states that "It's also to show the communities that we embrace them as citizens of this city, that we are in acceptance of their culture and the transition that they're going through," he says.
Brain-imaging studies have shown that music activates many diverse parts of the brain, including an overlap in where the brain processes music and language. Brains of people exposed to even casual musical training have an enhanced ability to generate the brain wave patterns associated with specific sounds, be they musical or spoken, said study leader Nina Kraus, director of the Auditory Neuroscience Laboratory at Northwestern University in Illinois. Musicians have subconsciously trained their brains to better recognize selective sound patterns, even as background noise goes up.
In contrast, people with certain developmental disorders, such as dyslexia, have a harder time hearing sounds amid the din. Musical experience could therefore be a key therapy for children with dyslexia and similar language-related disorders.
Harvard Medical School neuroscientist Gottfried Schlaug has found that stroke patients who have lost the ability to speak can be trained to say hundreds of phrases by singing them first. Schlaug demonstrated the results of intensive musical therapy on patients with lesions on the left sides of their brains, those areas most associated with language. Before the therapy, these stroke patients responded to questions with largely incoherent sounds and phrases. But after just a few minutes with therapists, who asked them to sing phrases and tap their hands to the rhythm, the patients could sing "Happy Birthday," recite their addresses, and communicate if they were thirsty.
"The underdeveloped systems on the right side of the brain that respond to music became enhanced and changed structures," Schlaug said at the press briefing.
"Teenagers are more susceptible to developing disorders like addiction and depression ... "The brain region traditionally associated with reward and motivation, called the nucleus accumbens, was activated similarly in adults and adolescents," said Moghaddam. "But the unique sensitivity of adolescent DS to reward anticipation indicates that, in this age group, reward can tap directly into a brain region that is critical for learning and habit formation." ... not only is reward expectancy processed differently in an adolescent brain, but also it can affect brain regions directly responsible for decision-making and action selection. ... "Adolescence is a time when the symptoms of most mental illnesses-such as schizophrenia and bipolar and eating disorders-are first manifested, so we believe that this is a critical period for preventing these illnesses," Moghaddam said."
