This Is What It's Like To Be Awake During Brain Surgery - 0 views

  •  
    The recent advent of brain-mapping technology-which allows doctors to create a precise digital replica of a person's brain cartography--has made more surgeons comfortable with the concept of keeping patients awake while they operate. This article profiles a woman, Brittany Capone, who's having open-brain surgery to remove a tumor that's dangerously close to a region in the brain that controls speech and the ability to comprehend language. By doing the operation while she is awake and speaking, her surgeon, Dr. Philip Gutin, can figure out exactly where the offending growth ends and the area of the brain called the Wernicke's center begins. This way, Gutin can see how close he can cut without permanently affecting his patient's ability to talk. What neurosurgeons are learning through mapping and documenting their experiences is also informing general knowledge about where brain structures are located and the slightly different positions they can take in different people.

Even A Few Years Of Music Training Benefits the Brain - 3 views

  •  
    This Scientific American blog article provides a handy run-down of research findings re: music's effect on the brain, including 1. Musicians are better able to process foreign languages because of their ability to hear differences in pitch, and have incredible abilities to detect speech in noise. Even those w/ a few years of music training showed more robust neural processing of sounds. Music "tones auditory fitness", critical for perceiving speech and distinguishing, recognizing and processing conversation in noisy environments. 2. Musical training and education may confer linguistic, mathematical, and spatial benefits, and promote social development/"team player" capacities.

Neuroscience and the Classroom - 3 views

  •  
    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.

Music and the brain - 4 views

  •  
    A South African scientist who was pregnant wanted to document what sounds actually reached the fetus during pregnancy. She designed a waterproof microphone that was put inside next to the fetus' neck. Outside music was recorded by the microphone proving that music can be heard in the womb. Music also stimulates the brain more than anything else scientist have tested and has been used in some cases to coax parts of the brain to take over the job of other, dead parts of the brain in stroke patients

Making Music Boosts Brain's Language Skills - 7 views

  •  
    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.

Hearing Metaphors Activates Brain Regions Involved in Sensory Experience - 2 views

  •  
    New brain imaging research at Emory University reveals that a region of the brain important for sensing texture through touch, the parietal operculum, is also activated when someone listens to a sentence with a textural metaphor. The same region is not activated when a similar sentence expressing the meaning of the metaphor is heard.

Cold and Lonely: Does Social Exclusion Literally Feel Cold? - 4 views

  •  
    Recent studies suggest that metaphors are more than just fancy literary devices and that there is a psychological basis for linking cold with feelings of social isolation. Psychologists Chen-Bo Zhong and Geoffrey Leonardelli from the University of Toronto's Rotman School of Management wanted to test the idea that social isolation might generate a physical feeling of coldness. In their first experiment, they divided a group of volunteers into two groups. One group recalled a personal experience in which they had been socially excluded-rejection from a club, for example. This was meant to tap into their feelings of isolation and loneliness. The other group recalled an experience in which they had been accepted into a group. Afterwards, volunteers were asked to estimate the temperature in the room. Those who recalled memories of being ostracized experienced the ambient temperature of the room as colder. In a second experiment, researchers triggered feelings of exclusion by having volunteers play a computer-simulated ball tossing game. The game was designed so that some of the volunteers had the ball tossed to them many times, but others were left out. Afterwards, all the volunteers rated the desirability of certain foods and beverages: hot coffee, crackers, an ice-cold Coke, an apple, and hot soup. The findings were striking. As reported in the September issue of Psychological Science, a journal of the Association for Psychological Science, the "unpopular" volunteers who had been ostracized during the computer game were much more likely than the others to want either hot soup or hot coffee. Their preference for warm food and drinks presumably resulted from physically feeling cold as a result of being excluded. "It's striking that people preferred hot coffee and soup more when socially excluded," Leonardelli said. "Our research suggests that warm chicken soup may be a literal coping mechanism for social isolation."

Wide Vocabulary & Brains - 0 views

  •  
    I chose this article because prior to posting this I was studying my SAT vocab. I was wondering if this would really help me. I found that "increased vocabulary knowledge correlates with increased grey matter density in a region of the parietal cortex that is well-located to mediate an association between meaning and sound (the posterior supramarginal gyrus). Further this region also shows sensitivity to acquiring a second language. Relative to monolingual English speakers, Italian-English bilinguals show increased grey matter density in the same region."

Imagine A Flying Pig: How Words Take Shape In The Brain : NPR - 3 views

  •  
    Just a few decades ago, many linguists thought the human brain had evolved a special module for language . It seemed plausible that our brains have some unique structure or system. After all, no animal can use language the way people can. However, in the 1990s, scientists began testing the language-module theory using "functional" MRI technology that let them watch the brain respond to words. And what they saw didn't look like a module, says Benjamin Bergen, a researcher at the University of California, San Diego, and author of the book _Louder Than Words_. "They found something totally surprising," Bergen says. "It's not just certain specific little regions in the brain, regions dedicated to language, that were lighting up. It was kind of a whole-brain type of process." The brain appears to be taking words, which are just arbitrary symbols, and translating them into things we can see or hear or do; language processing, rather than being a singular module, is "a highly distributed system" encompassing many areas of the brain. Our sensory experiences can also be applied to imagining novel concepts like "flying pigs". Our sensory capacities, ancestral features shared with our primate relatives, have been co-opted for more recent purposes, namely words and language. Bergen comments, "What evolution has done is to build a new machine, a capacity for language, something that nothing else in the known universe can do," he says. "And it's done so using the spare parts that it had lying around in the old primate brain."

Shakespeare and Wordsworth boost the brain, new research reveals - Telegraph - 0 views

  •  
    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.

Deaf People 'Feel Touch' With Hearing Part of Brain - 3 views

  •  
    Individuals who are born deaf use the "hearing" part of their brain to feel touch and to see objects, suggests new research that highlights the plasticity of the human brain. The new study, detailed online July 11 in The Journal of Neuroscience, shows that deaf people use the so-called auditory cortex to process both touch and visual stimuli much more than hearing individuals do.

MIT claims to have found a "language universal" that ties all languages together - 2 views

  •  
    Language takes an astonishing variety of forms across the world-to such a huge extent that a long-standing debate rages around the question of whether all languages have even a single property in common. Well, there's a new candidate for the elusive title of "language universal" according to a paper in this week's issue of PNAS.
