Are the 10% of people who are left-handed and of those whose language is located in the brain's right hemisphere the same? Is the location of language areas in the brain correlated to handedness? Through an innovative approach using a large psychometric and brain imaging database, researchers demonstrated that the location of language areas in the brain is independent of left- or right-handedness, except for a very small proportion of left-handed individuals whose right hemisphere is dominant for both manual work and language.

"In cultures with left-to-right orthography (e.g., English-speaking cultures) time appears to flow rightward, but in cultures with right-to-left orthography (e.g., Arabic-speaking cultures) time flows leftward." Participants who read regular text tended to press the left button for past-oriented phrases and the right button for future-oriented phrases, but participants who read mirrored text did the opposite.

Dyslexia is the most common learning disability in the U.S. Scientists are exploring how human brains learn to read, and are discovering new ways that brains with dyslexia can learn to cope. 2 areas on the left side of the brain are key for reading: 1. the left temporoparietal cortex: traditionally used to process spoken language. When learning to read, we start using it to sound out words. 2. the occipitotemporal cortex: part of the visual processing center, located at the base of our brain, behind our ears. A person who never learned to read uses this part of the brain to recognize objects - like a toaster or a chair. But, as we become fluent readers, we train this brain area to recognize letters and words visually. These words are called sight words: any word that you can see and instantly know without thinking about the letters and sounds. This requires retraining the brain. When recognizing a chair, the brain naturally sees it from many different angles - left, right, up, down - and, regardless of the perspective, the brain knows it is a chair. But that doesn't work for letters. Look at a lowercase 'b' from the backside of the page, and it looks like a lowercase 'd.' They are the same basic shape and, yet, two totally different letters. But, as it does with a chair, the brain wants to recognize them as the same object. Everyone - not just people with dyslexia - has to teach the brain not to conflate 'b' and 'd'. The good news: intervention and training can help. At the end of the six week training sessions with dyslexics, the brain areas typically associated with reading, in the left hemisphere, became more active. Additionally, right hemisphere areas started lighting up and helping out with the reading process. The lead scientist, Dr. Eden, says this is similar to what scientists see in stroke victims, where other parts of the brain start compensating.

Our brains are developed with two distinct groups, the left and right hemispheres, that think in two very different manners. The left brain processes information rationally, sequentially, and logically and uses language, while the right hemisphere processes information randomly and holistically, and uses visuals more. We as humans have a dominant side of the brain which we prefer to use, and by catering to this dominant side (e.g. learning through listening for the left side, and learning through visuals for the right), we are able to learn more and understand more easily. We are not able to survive by only using one side of our brain, and it is necessary to use both and train both.

Author Sena Moore writes about how music can re-wire our brains for speech. Singing and speaking activate similar areas on both sides of the brain, primarily in the motor production and sensory feedback areas. Singing, however, also activates the right hemisphere in some areas more strongly than the left. Speech is a left-hemisphere-dominate function. In other words, similar networks in the brain associated with vocal production are activated when a person is singing and when s/he is speaking. And the "stronger right hemisphere" activation supports the clinical observation that those who cannot speak because of damage to the left hemisphere speech areas known as Broca's area can still produce words by singing them.

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.

A Liverpool University study found reading poetry lights up both the left part of the brain concerned with language, as well as the right hemisphere, an area that relates to autobiographical memory and emotion. Reading triggers "reappraisal mechanisms" that cause people to reflect on their own experiences in light of what they read. The study might also suggest that word choice and sound are crucial elements in creating beneficial literary experiences: more "challenging" prose and poetry (striking wording/phrasing, complex syntax) sparks far more electrical activity in the brain than more pedestrian translations of those passages.

Excellent study. "While it has long been recognized that certain areas in the brain's left hemisphere enable us to understand and produce language, scientists are still figuring out exactly how those areas divvy up the highly complex processes necessary to comprehend and produce language. ... Two brain areas called Broca's region and Wernicke's region serve as the main computing hubs underlying language processing, with dense bundles of nerve fibers linking the two ... Working with patients suffering from language impairments because of a variety of neurodegenerative diseases, Wilsons' team used brain imaging and language tests to disentangle the roles played by the two pathways. ... The study marks the first time it has been shown that upper and lower tracts play distinct functional roles in language processing."

While the left hemisphere of the brain is where the processing and understanding of language is, different sections of the brain control different parts of language. Two separate areas of the brain control the ability to remember and understand specific words, and the other controls how we construct sentences and make sense of them. If one of these sections is damaged, the other can still work properly, so it is possible to be able to remember words and what they mean but not know how to create sentences.

Screens have changed our reading patterns from the linear, left-to-right sequence of years past to a wild skimming and skipping pattern as we hunt for important words and information. One 2006 study of the eye movements of 232 people looking at Web pages found they read in an "F" pattern, scanning all the way across the top line of text but only halfway across the next few lines, eventually sliding their eyes down the left side of the page in a vertical movement toward the bottom. None of this is good for our ability to comprehend deeply, scientists say. Reading text punctuated with links leads to weaker comprehension than reading plain text, several studies have shown. A 2007 study involving 100 people found that a multimedia presentation mixing words, sounds and moving pictures resulted in lower comprehension than reading plain text did. Slow reading means a return to a continuous, linear pattern, in a quiet environment free of distractions. Advocates recommend setting aside at least 30 to 45 minutes in a comfortable chair far from cellphones and computers. Some suggest scheduling time like an exercise session. Many recommend taking occasional notes to deepen engagement with the text.

Sometimes ideas that originate in science seep out into the broader culture and take on a life of their own. It's still common to hear people referred to as "anal," a Freudian idea that no longer has much currency in contemporary psychology.

3D interactive brain with labels: can select from left menu particular areas to look at, such as Broca's and Wernicke's

"Consistent with the Sapir-Whorf hypothesis, participants were quicker at distinguishing between a 'green' and a 'blue' than between two 'greens' or two 'blues', but crucially, this advantage only pertained when the colours appeared on the right-hand side of space [when the brain is using the "language-dominant left hemisphere"]."

"Most people implicitly associate positive ideas with "right" and negative ideas with "left"....The meanings of words in English, Dutch, and Spanish are related to the way people type them on the QWERTY keyboard. Words with more right-hand letters are rated as more positive in emotional valence than words with more left-hand letters, consistent with right-handers' tendency to implicitly associate "good" with "right.""

"Even when daydreaming, there is a tremendous amount of communication happening between different areas in the brain... The fact that these areas are synchronized has led many scientists to presume that they are all part of an interconnected network called a resting-state network. ... that these resting-state networks look essentially normal in people missing the corpus callosum link... [it] highlights the brain's remarkable plasticity... the findings are significant when considering the link between brain connections and autism or schizophrenia."

The chair squeaked quietly as I fidgeted, swiveling left, right, left. I sat toward the back of a long wooden table flanked by my fellow graduate students, while a pair of eminent biologists led a discussion on how to talk to skeptical non-scientists about evolution.

After Great Britain left the European Union this year, its said that it would try to trade more with China. However, Mandarin Chinese education in Britain is not very extensive, and both the government private industries are taking a new approach - immersion and bilingual schools - to try to teach young children Mandarin. The UK hopes for 5000 fluent students by 2020.

Why does "left" mean liberal and "right" mean conservative? To answer this question, the article probes into how this political terminology originated from the physical location of politicians in the 1789 French National Assembly, which was the parliament France formed after the French Revolution.

Lera Boroditsky, cognitive science professor at UC San Diego notes, "...a growing body of research is documenting how experience with language radically restructures the brain. People who were deprived of access to language as children (e.g., deaf individuals without access to speakers of sign languages) show patterns of neural connectivity that are radically different from those with early language exposure and are cognitively different from peers who had early language access. The later in life that first exposure to language occurs, the more pronounced and cemented the consequences. Further, speakers of different languages develop different cognitive skills and predispositions, as shaped by the structures and patterns of their languages. Experience with languages in different modalities (e.g., spoken versus signed) also develops predictable differences in cognitive abilities outside the boundaries of language. For example, speakers of sign languages develop different visuospatial attention skills than those who only use spoken language. Exposure to written language also restructures the brain, even when acquired late in life. Even seemingly surface properties, such as writing direction (left-to-right or right-to-left), have profound consequences for how people attend to, imagine, and organize information. The normal human brain that is the subject of study in neuroscience is a "languaged" brain. It has come to be the way it is through a personal history of language use within an individual's lifetime. It also actively and dynamically uses linguistic resources (the categories, constructions, and distinctions available in language) as it processes incoming information from across the senses.
