Really interesting article about excessive texting leading to brain damage.

"The researchers can't be sure, but they think the remission of the man's stammer is likely related to his cerebellum damage, which may have had the effect of inhibiting excessive neural activation in that structure."

Just seeing a list of negative words for a few seconds will make a highly anxious or depressed person feel worse, and the more you ruminate on them, the more you can actually damage key structures that regulate your memory, feelings, and emotions.But negative words, spoken with anger, do even more damage. They send alarm messages through the brain, interfering with the decision making centers in the frontal lobe, and this increases a person's propensity to act irrationally. Fear-provoking words-like poverty, illness, and death-also stimulate the brain in negative ways. And even if these fearful thoughts are not real, other parts of your brain (like the thalamus and amygdala) react to negative fantasies as though they were actual threats occurring in the outside world. Curiously, we seem to be hardwired to worry-perhaps an artifact of old memories carried over from ancestral times when there were countless threats to our survival.

Stephen Wilson, an associate professor in the University of Arizona's Department of Speech, Language, and Hearing Sciences, studied the upper and lower white-matter connecting pathways between Broca's region and Wernicke's region: the two areas of the brain that are hubs for language processing. Brain imaging and language tests were used to examine patients suffering from language impairments caused by neurodegeneration. Wilson discovered the pathways have distinct functions. Damage to the lower pathway affects lexicon and semantics: "You forget the name of things, you forget the meaning of words. But surprisingly, you're extremely good at constructing sentences." Conversely, damage to the upper pathway creates problems in syntactic processing and figuring out the relationship between words in a sentence.

Language isn't found in just one part of the brain but rather in separate individual parts that are responsible for different aspects of language. Neurodegentive diseases that target specific areas of the brain affecting language, only have a partial effect on the patients ability to understand and communicate.

this is an article that (eventually) talks about how words, or verbal abuse, affects brain development.

This article examines the relationship between borrowed language and bilingual speakers' grasp of their known languages. It highlights the implicit understanding of grammar rules that bilingual speakers naturally develop for their languages and debunks the misconception that loan words damage a speaker's understanding of another language. The article described a study on bilingual speakers in Ottawa-Hull who combined language (code-switching or "mish-mashing") while still following the correct grammatical structures. (i.e. "If a verb was borrowed from English, it was conjugated in strict accordance with the rules for conjugating French verbs..") It also reminded readers that pronunciation is not intrinsically tied to language proficiency.

This article is about a study of around 260 students ages 11-18 years old at a secondary school in the Midlands to determine if the increased use of technology had hindered students' ability in school. It was found that about six out of ten students copied directly from sources with over a quarter of them not realizing that it was plagiarism. The study also found that the increase use of modern technology has made more students use "text-speak" in their work at school. Text-speak is made up of shortcuts usually used when texting another person. Teachers are having a harder time understand their students' work because of the usage of text-speak, thus proving the negative impacts of the increased use of modern technology on students.

Comparing two types of brain damage, researchers believe "the semantic system of the brain is comprised of at least two components - a core representation of knowledge, and an overall control system that navigates through the corridors of the mind finding and comparing meanings."

A Johns Hopkins study found that damage to a key structure in the brain may explain why some stroke patients can't perceive sarcasm. Researchers looked at 24 people who had experienced a stroke in the right hemispheres of their brains. Those with damage to the right sagittal stratum tended to have trouble recognizing sarcasm, the researchers found. This bundle of neural fibers connects a number of brain regions, including those that process auditory and visual information. Sarcasm can be hard to interpret; it's a complex way to communicate. First, the person has to 1. understand the literal meaning of what someone says 2. detect the components of sarcasm: a wider range of pitch, greater emphatic stress, briefer pauses, lengthened syllables and intensified loudness relative to sincere speech "There're a number of cues people use, and it's both facial cues and tone of voice," noted Dr. Argye Hillis, a professor of neurology at Johns Hopkins University School of Medicine.

The idea behind the Weapon of Choice Project was to create a visual representation of the emotional damage words can do, in order to spur conversations re: verbal abuse, domestic violence, bullying, and child abuse. Professional makeup artists generously donated their time to the project. The artists applied makeup to each participant to simulate an injury, and the hurtful word chosen by the participant was then incorporated.

This site is very insightful as to the differences in language development in the brain between those that learn a second language in childhood and those that learn the language as adults. It explains briefly the idea of a critical period and discusses the interesting aspects that come along with learning a second language later in life. It mentions Broca's and Wernicke's area.

Got turned onto this course at the recent "Learning and the Brain" conference in San Francisco, as one of the presenters, Mary-Helen Immordino-Yang, an affective neuroscientist and human development psychologist, is one of the co-developers of this introductory neuroscience course: free, thanks to a generous Annenberg Foundation grant. The course units cover several topics pertinent to Words R Us, including brain anatomy; language, music, and the brain; language and brain damage; emotions, empathy, and behavior; and cognitive functioning and development as it relates to reading and writing. The site also offers lots of embedded course materials, visuals, and videos. Though originally geared towards K-12 teachers, other educators, researchers, and adult learners who want to learn more about current issues in education, students-especially those considering careers in education, psychology, neuroscience, and/or the biological sciences-might find this course useful.

There are ways to reduce your risk of having a stroke - for example, you can exercise more and not smoke. But should a stroke occur, you might also be able to reduce your risk of losing brain function if you are a speaker of more than one language.

Dr. Thomas Bak, one of the study's authors, posits that language learning helps brains build "cognitive reserve": a rich network of neural connections - highways that can can still carry the busy traffic of thoughts even if a few bridges are destroyed, as via a stroke. "People with more mental activities have more interconnected brains, which are able to deal better with potential damage," Bak says. He likens language learning's effect on the brain to swimming's ability to strengthen the body. Learning a language at any stage in life provides a thorough workout, but other cognitive "exercises," such as doing puzzles or playing a musical instrument, might also benefit stroke recovery, he said. The research applies to the larger concept of neuroplasticity, in that the brain is dynamic and can adapt to new challenges when properly conditioned,

"...for many Swedes, gender equality is not enough. Many are pushing for the Nordic nation to be not simply gender-equal but gender-neutral. ... Just days after International Women's Day a new pronoun, hen (pronounced like the bird in English), was added to the online version of the country's National Encyclopedia. ... critics believe it can be psychologically and socially damaging, especially for children ... toddlers cannot weigh arguments for and against linguistic interventions and they do not conceive of or analyze gender roles in the way that adults do ... One Swedish school got rid of its toy cars because boys 'gender-coded' them and ascribed the cars higher status than other toys."

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.

According to research led by V. S. Ramachandran, director of the Center for Brain and Cognition at the University of California, San Diego, a region of the brain known as the angular gyrus is probably at least partly responsible for the human ability to understand metaphor. Ramachandran and colleagues tested four right-handed patients with damage to the left angular gyrus. Fluent in English and otherwise intelligent and mentally lucid, the patients showed gross deficits in comprehending such common proverbs as "the grass is always greener on the other side" and "an empty vessel makes more noise." Asked to explain the sayings, the patients tended give responses that were literal. The metaphorical meaning escaped them almost entirely.

"When a surgeon cut into Henry Molaison's skull to treat him for epilepsy, he inadvertently created the most important brain-research subject of our time - a man who could no longer remember, who taught us everything we know about memory. Six decades later, another daring researcher is cutting into Henry's brain. Another revolution in brain science is about to begin."
