Doctors at Beth Israel Deaconess Medical Center in Boston, Massachusetts, are treating stroke patients who have little or no spontaneous speech by associating melodies with words and phrases. "Music, and music-making, is really a very special form of a tool or an intervention that can be used to treat neurological disorders, said Dr. Gottfried Schlaug, associate professor of neurology at Beth Israel and Harvard University.

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.

I found this article interesting because it showed that humans are equally inclined to music, as they are to language. Also, music stimulates the same parts of the brain that language does.

(This article was by my college friend, Quinn Eastman, who's a trained scientist and science writer for Emory University.) Listening to metaphors involving arms or legs loops in a region of the brain responsible for visual perception of those body parts, scientists have discovered. The finding, recently published in Brain & Language, is another example of how neuroscience studies are providing evidence for "grounded cognition" - the idea that comprehension of abstract concepts in the brain is built upon concrete experiences, a proposal whose history extends back millennia to Aristotle. When study participants heard sentences that included phrases such as "shoulder responsibility," "foot the bill" or "twist my arm", they tended to engage a region of the brain called the left extrastriate body area or EBA. The same level of activation was not seen when participants heard literal sentences containing phrases with a similar meaning, such as "take responsibility" or "pay the bill." The study included 12 right-handed, English-speaking people, and blood flow in their brains was monitored by functional MRI (magnetic resonance imaging). "The EBA is part of the extrastriate visual cortex, and it was known to be involved in identifying body parts," says senior author Krish Sathian, MD, PhD, professor of neurology, rehabilitation medicine, and psychology at Emory University. "We found that the metaphor selectivity of the EBA matches its visual selectivity." The EBA was not activated when study participants heard literal, non-metaphorical sentences describing body parts. "This suggests that deep semantic processing is needed to recruit the EBA, over and above routine use of the words for body parts," Sathian says. Sathian's research team had previously observed that metaphors involving the sense of touch, such as "a rough day", activate a region of the brain important for sensing texture. In addition, other researchers have shown t

Interesting follow-up to the handout on reading creating simulations in the brain. The brain, it seems, does not make much of a distinction between reading about an experience and encountering it in real life; in each case, the same neurological regions are stimulated. Reading provides a strong simulation of reality.

The amygdala is an almond shaped mass of nuclei located deep within the temporal lobe of the brain. It is a limbic system structure that is involved in many of our emotions and motivations, particularly those that are related to survival. The amygdala is involved in the processing of emotions such as fear, anger and pleasure. > Additional link provided to other neurological terms such as the hippocampus.

People familiar with more than one language showed a later onset of dementia, according to a new study from Indian researchers. Multilingualism appeared to stave off dementia onset in several diagnostic categories, including front temporal and vascular dementia as well as Alzheimer's, according to the researchers' report in the online version of Neurology.

An infant's mother tongue creates neural patterns that the unconscious brain retains years later, even if the child totally stops using the language, (as can happen in cases of international adoption) according to a new joint study by scientists at the Montreal Neurological Institute and Hospital. The study offers the first neural evidence that traces of the "lost" language remain in the brain and suggests that early-acquired information is not only maintained in the brain, but unconsciously influences brain processing for years, perhaps for life -- potentially indicating a special status for information acquired during optimal periods of development. This could counter arguments not only within the field of language acquisition, but across domains, that neural representations are overwritten or lost from the brain over time.

This article is about how Tourette syndrome may actually increase children's abilities for language in the areas of phonology and morphology. Interestingly, the article speaks about how Tourette syndrome may be a neurological disorder which increases the function of the part of the brain related to recognizing sounds despite causing a decreased ability in motor function.

Recognition of subtle emotional cues may be developmental, according to neurological research. At the McLean Hospital in Belmont, Mass., Deborah Yurgelun-Todd and a group of researchers have studied how adolescents perceive emotion as compared to adults. The scientists looked at the brains of 18 children between the ages of 10 and 18 and compared them to 16 adults using functional magnetic resonance imaging (fMRI). Both groups were shown pictures of adult faces and asked to identify the emotion on the faces. Using fMRI, the researchers could trace what part of the brain responded as subjects were asked to identify the expression depicted in the picture. The results surprised the researchers. The adults correctly identified the expression as fear. Yet the teens answered "shocked, surprised, angry." Moreover, teens and adults used different parts of their brains to process what they were feeling. The teens mostly used the amygdala, a small almond shaped region that guides instinctual or "gut" reactions, while the adults relied on the frontal cortex, which governs reason and planning. As the teens got older, however, the center of activity shifted more toward the frontal cortex and away from the cruder response of the amygdala. Yurgelun-Todd, director of neuropsychology and cognitive neuroimaging at McLean Hospital believes the study goes partway to understanding why the teenage years seem so emotionally turbulent. The teens seemed not only to be misreading the feelings on the adult's face, but they reacted strongly from an area deep inside the brain. The frontal cortex helped the adults distinguish fear from shock or surprise. Often called the executive or CEO of the brain, the frontal cortex gives adults the ability to distinguish a subtlety of expression: "Was this really fear or was it surprise or shock?" For the teens, this area wasn't fully operating.

Nice overview of the neurological and other benefits conferred by bilingualism. Being fluent in two languages, particularly from early childhood, not only enhances a person's ability to concentrate, but might also protect against the onset of dementia and other age-related cognitive decline. More recently, scientists have discovered that bilingual adults have denser gray matter (brain tissue packed with information-processing nerve cells and fibers), especially in the brain's left hemisphere, where most language and communication skills are controlled. The effect is strongest in people who learned a second language before the age of five and in those who are most proficient at their second language. This finding suggests that being bilingual from an early age significantly alters the brain's structure.

The age at which children learn a second language can have a significant bearing on the structure of their adult brain, according to a new joint study by the Montreal Neurological Institute and Hospital -- The Neuro at McGill University and Oxford University. The study concludes that the pattern of brain development is similar if you learn one or two language from birth. However, learning a second language later on in childhood after gaining proficiency in the first (native) language does in fact modify the brain's structure, specifically the brain's inferior frontal cortex. The left inferior frontal cortex became thicker and the right inferior frontal cortex became thinner. The cortex is a multi-layered mass of neurons that plays a major role in cognitive functions such as thought, language, consciousness and memory. The study suggests that the task of acquiring a second language after infancy stimulates new neural growth and connections among neurons in ways seen in acquiring complex motor skills such as juggling. The study's authors speculate that the difficulty that some people have in learning a second language later in life could be explained at the structural level.

Scientists are reporting in the journal Science that they have identified specialized brain cells that help us understand what a speaker really means. These cells do this by keeping track of changes in the pitch of the voice. "We found that there were groups of neurons that were specialized and dedicated just for the processing of pitch," says Dr. Eddie Chang, a professor of neurological surgery at the University of California, San Francisco. Chang says these neurons allow the brain to detect "the melody of speech," or intonation, while other specialized brain cells identify vowels and consonants. "Intonation is about how we say things," Chang says. "It's important because we can change the meaning, even - without actually changing the words themselves." The identification of specialized cells that track intonation shows just how much importance the human brain assigns to hearing, says Nina Kraus, a neurobiologist who runs the Auditory Neuroscience Laboratory at Northwestern University. "Processing sound is one of the most complex jobs that we ask our brain to do," Kraus says. And it's a skill that some brains learn better than others, she says. Apparently, musicians, according to a study conducted by Kraus, are better than non-musicians at recognizing the subtle tonal changes found in Mandarin Chinese. On the other hand, recognizing intonation is a skill that's often impaired in people with autism, Kraus says. "A typically developing child will process those pitch contours very precisely," Kraus says. "But some kids on the autism spectrum don't. They understand the words you are saying, but they are not understanding how you mean it." The new study suggests that may be because the brain cells that usually keep track of pitch aren't working the way they should.

A 2013 joint study, conducted by the Montreal Neurological Institute and Hospital -- The Neuro at McGill University and Oxford University, concludes that the pattern of brain development is similar if you learn one or two languages from birth. However, learning a second language later on in childhood, after gaining proficiency in the first (native) language, does in fact, modify the brain's structure, specifically the brain's inferior frontal cortex. The left inferior frontal cortex became thicker and the right inferior frontal cortex became thinner. The cortex is a multi-layered mass of neurons that plays a major role in cognitive functions such as thought, language, consciousness and memory. The study suggests that the task of acquiring a second language after infancy stimulates new neural growth and connections among neurons in ways seen in acquiring complex motor skills such as juggling. The study's authors speculate that the difficulty that some people have in learning a second language later in life could be explained at the structural level. "The later in childhood that the second language is acquired, the greater are the changes in the inferior frontal cortex," said Dr. Denise Klein, researcher in The Neuro's Cognitive Neuroscience Unit and a lead author on the paper published in the journal Brain and Language. "Our results provide structural evidence that age of acquisition is crucial in laying down the structure for language learning."
