Three amazing stories about language: "We meet a woman who taught a 27-year-old man the first words of his life, hear a firsthand account of what it feels like to have the language center of your brain wiped out by a stroke, and retrace the birth of a brand new language 30 years ago."

We use both sides of our brain for speech, New York University researchers have discovered: a finding that alters previous conceptions about neurological activity. Many in the scientific community have posited that both speech and language are lateralized -- that is, we use only one side of our brains for speech, which involves listening and speaking, and language, which involves constructing and understanding sentences. However, the conclusions pertaining to speech generally stem from studies that rely on indirect measurements of brain activity, raising questions about characterizing speech as lateralized.
In their examination, the researchers tested the parts of the brain that were used during speech. Here, the study's subjects were asked to repeat two "non-words" -- "kig" and "pob." Using non-words as a prompt to gauge neurological activity, the researchers were able to isolate speech from language.
An analysis of brain activity as patients engaged in speech tasks showed that both sides of the brain were used -- that is, speech is, in fact, bi-lateral. The results also offer insights into addressing speech-related inhibitions caused by stroke or injury and lay the groundwork for better rehabilitation methods.
This experiment dealt with patients who have Aphasia (an impairment of language due to a stroke or brain injury) and mapped out the brain to see what areas of the brain are affected and how their brains differ.
Around the world more than half (around 60 to 75 percent) speak at least two languages. Most countries have more than one official national language. For example south Africa has 11. So being monolingual like most native english speakers are, we are becoming the minority.
Multilingualism serves an extremely practical purpose. Languages change and develop through social pressures. Over time, different groups of early humans would have found themselves speaking different languages. Then, in order to communicate with other groups - for trade, travel and so on - it would have been necessary for some members of a family or band to speak other tongues.
We can get some sense of how prevalent multilingualism may have been from the few hunter-gatherer peoples who survive today. "If you look at modern hunter-gatherers, they are almost all multilingual," says Thomas Bak, a cognitive neurologist who studies the science of languages at the University of Edinburgh. "The rule is that one mustn't marry anyone in the same tribe or clan to have a child - it's taboo. So every single child's mum and dad speak a different language."
The article also provides a useful summary of the benefits of speaking at least one other language: bilinguals outperform monolinguals in a range of cognitive and social tasks from verbal and nonverbal tests to how well they can read other people. Greater empathy is thought to be because bilinguals are better at blocking out their own feelings and beliefs in order to concentrate on the other person's. Bilingualism can also delay the onset of dementia and increase cognitive recovery after a stroke. And in addition to social and cultural benefits, bil
Over the years, we have found that our words come from different parts of the brain. In addition the part of the brain which we use to formulate thoughts into sentences, we also use the part of the brain that deals with emotion when we swear. Researchers discovered that patients with neurodegenerative diseases like a stroke, were still able to swear. Studying patients with Tourette syndrome have also proved that swearing uses many areas of the brain. Since swearing involves the emotional part of the brain, we know that profanity is used to express intense emotions.
Regular speech is generated in the left hemisphere, in an area of the brain close to the surface. The cerebral cortex, or "gray matter," is often associated with higher thought processes such as thought and action. "It's sophisticated," says Bergen, "and comports with the idea of what it means to be human."
Swearing, on the other hand, is generated much deeper in the brain, in regions that are older and more primitive in evolutionary terms, says Bergen. These regions are often found in the right hemisphere in the brain's emotional center, the limbic system."These are words that express intense emotions-surprise, frustration, anger, happiness, fear," says psychologist and linguist Timothy Jay, who began studying profanity more than 40 years ago."[Swearing] serves my need to vent, and it conveys my emotions to other people very effectively and symbolically," he says. "Where other animals like to bite and scratch each other, I can say 'f*ck you' and you get my contempt-I don't have to do it physically."
Profanity serves other purposes, too. Lovers use it as part of enticing sex talk; athletes and soldiers use it to forge camaraderie; and people in positions of power use it to reaffirm their superiority. Profanity is even used as a celebratory expression, says Adams, citing "F*ck yeah!" as an example.
The meaning of a profanity, like any other word, changes with time, culture and context. While swear words have been around since Greek and Roman times, and maybe even earlier, the types of things people consider offensive have changed. "People of the Middle Ages had no problems talking about sex or excrement, that was not their hang-up," Adams explains. "Their hang-up was talking about God disrespectfully...so that was what a profanity was."
The left hemisphere of the brain is responsible for emotions like happiness, sadness, and anger. The part of the brain that we use to formulate thoughts into sentences is that part that we also use to deal with emotion when we swear. Different studies done on people found with brain issues/diseases allowed researchers to understand that profanity is used to express the extreme emotions.
Multilingualism has been shown to have many social, psychological and lifestyle advantages, including superior ability to concentrate, solve problems and focus, better mental flexibility and multitasking skills. Moreover, researchers are finding a swathe of health benefits from speaking more than one language, including faster stroke recovery and delayed onset of dementia. A steady stream of studies over the past decade has shown that bilinguals outperform monolinguals in a range of cognitive and social tasks from verbal and nonverbal tests to how well they can read other people. Greater empathy is thought to be because bilinguals are better at blocking out their own feelings and beliefs in order to concentrate on the other person's.
