Article reports on the research of Dr. Charles Limb, of Johns Hopkins. Through fMRI, Limb found the brains of jazz musicians engaged with other musicians in spontaneous improvisation show robust activation in the same brain areas traditionally associated with spoken language and syntax. In other words, improvisational jazz conversations "take root in the brain as a language," Limb said. However, the areas of the brain associated with meaning are not activated.

Developmentally, teens are at particular risk for reckless online behavior, including secrecy regarding social networking. Many people - adults and kids alike - view likes, loves, comments and followers as a barometer for popularity, even within a smaller, closed group. Teens can quickly get caught up in the feedback loop, posting and sharing images and videos that they believe will gain the largest reaction. Over time, teens' own values may become convoluted within an online world of instantaneous feedback, and their behavior online can become based on their "all about the likes" values rather than their real-life values. There is a very real biological basis for this behavior. The combination of social media pressure and an underdeveloped prefrontal cortex, the region of the brain that helps us rationalize decisions, control impulsivity and make judgments, can contribute to offensive online posts. In a recent study, researchers at the University of California, Los Angeles, found that the areas of teens' brains focused on reward processing and social cognition are similarly activated when they think about money and sex - and when they view a photo receiving lots of likes on social media. When teens viewed photos deemed risky, researchers found the brain regions focused on cognitive control were not activated as much, suggesting that it could be harder for them to make good decisions when viewing images or videos that are graphic in nature.

Researchers from King's College London Institute of Psychiatry, in collaboration with Bellvitge Biomedical Research Institute (IDIBELL) and the University of Barcelona, mapped the neural pathways involved in word learning among humans. They found that the arcuate fasciculus, a collection of nerve fibres connecting auditory regions at the temporal lobe with the motor area located at the frontal lobe in the left hemisphere of the brain, allows the 'sound' of a word to be connected to the regions responsible for its articulation. Differences in the development of these auditory-motor connections may explain differences in people's ability to learn words. Researchers used diffusion tensor imaging to image the structure of the brain before a word learning task and functional MRI, to detect the regions in the brain that were most active during the task. They found a strong relationship between the ability to remember words and the structure of arcuate fasciculus, which connects two brain areas: the territory of Wernicke, related to auditory language decoding, and Broca's area, which coordinates the movements associated with speech and the language processing. In participants able to learn words more successfully their arcuate fasciculus was more myelinated i.e. the nervous tissue facilitated faster conduction of the electrical signal. In addition the activity between the two regions was more co-ordinated in these participants. Dr Catani concludes, "Now we understand that this is how we learn new words, our concern is that children will have less vocabulary as much of their interaction is via screen, text and email rather than using their external prosthetic memory. This research reinforces the need for us to maintain the oral tradition of talking to our children."

Negative thinking= detrimental both mentally and physically; it inhibits one's ability to bounce back from life's inevitable stresses. Negative feelings activate a region of the brain called the amygdala, which is involved in processing fear and anxiety and other emotions. Dr. Richard J. Davidson, a neuroscientist and founder of the Center for Healthy Minds at the University of Wisconsin - Madison, has shown that people in whom the amygdala recovers slowly from a threat are at greater risk for a variety of health problems than those in whom it recovers quickly. Both he and Dr. Fredrickson and their colleagues have demonstrated that the brain is "plastic," or capable of generating new cells and pathways, and it is possible to train the circuitry in the brain to promote more positive responses. That is, a person can learn to be more positive by practicing certain skills that foster positivity. 8 suggested activities to help bolster those skills: 1.Do good things for other people. 2.Appreciate the world around you. 3.Develop and bolster relationships. 4.Establish goals that can be accomplished. 5.Learn something new. 6.Choose to accept yourself, flaws and all. 7.Practice resilience. 8.Practice mindfulness.

Born between 1995 and 2012, teens are growing up with smartphones, have an Instagram account before they start high school, and do not remember a time before the Internet. There is compelling evidence that the devices we've placed in young people's hands are having profound effects on their lives-and making them seriously unhappy.. Some interesting (and disturbing) findings: 1. A 2017 survey of more than 5,000 American teens found that three out of four owned an iPhone. 2. While teens are physically safer than they've ever been, they're also more isolated and more subject to psychological harm. Rates of teen depression and suicide have skyrocketed since 2011. In addition, the number of teens who get together with their friends nearly every day dropped by more than 40 percent from 2000 to 2015; the decline has been especially steep recently. It's not only a matter of fewer kids partying; fewer kids are spending time simply hanging out. 3. Teens who spend more time than average on screen activities are more likely to be unhappy, and those who spend more time than average on nonscreen activities are more likely to be happy. 4. Girls have also borne the brunt of the rise in depressive symptoms among today's teens. Boys' depressive symptoms increased by 21 percent from 2012 to 2015, while girls' increased by 50 percent-more than twice as much. The rise in suicide, too, is more pronounced among girls. While boys tend to bully one another physically, girls are more likely to do so by undermining a victim's social status or relationships. Social media give middle- and high-school girls a platform to ostracize and exclude other girls 24/7. 5. Sleep deprivation: nearly all teens sleep with their phones in close proximity, and the devices are interfering with sleep: Many teens now sleep less than seven hours most nights. Sleep experts say that teens should get about nine hours of sleep a night; a teen who is getting less than seven hours a night is signific

Dr. Joy Hirsch, head of Memorial Sloan-Kettering Hospital's functional M.R.I. Laboratory, and her graduate student, Karl Kim, found that second languages are stored differently in the human brain, depending on when they are learned. Babies who learn two languages simultaneously, and apparently effortlessly, have a single brain region for generating complex speech, researchers say. But people who learn a second language in adolescence or adulthood possess two such brain regions, one for each language. To explore where languages lie in the brain, Dr. Hirsch recruited 12 healthy bilingual people from New York City. Ten different languages were represented in the group. Half had learned two languages in infancy. The other half began learning a second language around age 11 and had acquired fluency by 19 after living in the country where the language was spoken. With their heads inside the M.R.I. machine, subjects thought silently about what they had done the day before using complex sentences, first in one language, then in the other. The machine detected increases in blood flow, indicating where in the brain this thinking took place. Activity was noted in Wernicke's area, a region devoted to understanding the meaning of words and the subject matter of spoken language, or semantics, as well as Broca's area, a region dedicated to the execution of speech, as well as some deep grammatical aspects of language. None of the 12 bilinguals had two separate Wernicke's areas, Dr. Hirsch said. But there were dramatic differences in Broca's areas, Dr. Hirsch said. In people who had learned both languages in infancy, there was only one uniform Broca's region for both languages, a dot of tissue containing about 30,000 neurons. Among those who had learned a second language in adolescence, however, Broca's area seemed to be divided into two distinct areas. Only one area was activated for each language. These two areas lay close to each other but were always separate, Dr. Hirsch s

Gratitude is a common aspect of social interaction, yet relatively little is known about the neural bases of gratitude expression, nor how gratitude expression may lead to longer-term effects on brain activity. This Indiana University study tested whether gratitude letter-writing had benefits on the emotional health of depressed patients. Researchers found that a simple gratitude writing intervention was associated with significantly greater and lasting neural sensitivity to gratitude - subjects who participated in gratitude letter writing showed both behavioral increases in gratitude and significantly greater neural modulation by gratitude in the medial prefrontal cortex three months later.

This article talks about how even though learning how to program a computer seems like learning a new language, computer language is actually processed through a different area of the brain than when language is processed. It says that it activates the multiple demand network, which is also activated by complex cognitive tasks such as solving math problems or crossword puzzles. However, it appears to rely on different parts of the network than math or logic problems do, which suggests that coding does not precisely replicate the cognitive demands of mathematics either. The article says that researchers didn't find any regions that appear to be exclusively devoted to programming. They also suggest that understanding computer code cannot be categorized as a language-based or math-based skill. Instead, they think it might require a combination of both skills, even though the brain regions don't reflect it.

This study found that smokers' who performed self-affirming activities were less defensive and more responsive to cigarette warning ads and quitting smoking than smokers who did not perform these activities.

This article talked about the relationship between music and language. For a while, it was believed that language and music used different hemispheres of the brain, but this article looked into various studies that proved otherwise. One example that it explained was that growing up speaking a tonal language, such as Mandarin, can make people more sensitive to pitch changes and interval differences between notes.

This article describes how music and language affect each other in the brain, as well as ways that they can influence other aspects of learning. It also describes their similarity in brain activity.

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.

Swearing is a motor activity with a strong emotional content. The brain processes swear words and normal words differently. The brain stores swear words that are "emotionally charged" as whole units. The brain relies on the limbic system, which controls memory, emotion, and behavior, and the basal ganglia, which controls motor functions and impulse control, to process the "swear words".

This is an interesting correlation, but is it really causation?

Wouldn't the rigor of classes taken and other extracurricular activities also play a role in GPA? Wouldn't that also be a variable in their research? And a stalker button? Why would they even install that anyway?

Is social media good for you, or bad? Well, it's complicated. A UC San Diego study of 12 million Facebook users suggests that using Facebook is associated with living longer -- when it serves to maintain and enhance your real-world social ties. Those on Facebook with highest levels of offline social integration -- as measured by posting more photos, which suggests face-to-face social activity -- have the greatest longevity. Online-only social interactions, like writing wall posts and messages, showed a nonlinear relationship: Moderate levels were associated with the lowest mortality. Facebook users who accepted the most friendships also lived longest.

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.

Like a human's brain, a dog's brain responds to the meaning of a word and how the word is said. And like with a human's brain, the dog's left hemisphere reacts to meaning and the right hemisphere reacts to intonation. In the study, words were said to dogs in positive and neutral tones, but only positive words spoken in a positive tone prompted strong activity in the brain's reward center. This study suggested that non-primates could process meaning and emotion long before humans could talk.

Some of the "2016 is awful" rhetoric might be about the way we all consumed the headlines this year. Amy Mitchell, director of Journalism Research at the Pew Research Center, says what we've been witnessing in news consumption trends over the last few years has changed us. "A lot of the shift to digital is presenting a news experience that is more mixed in with other kinds of activities," she says. "You don't necessarily go online looking for news each and every time. Somebody shares it, somebody emails it to you, somebody texts a link. And so many Americans are bumping into the news throughout the course of the day." Nikki Usher, a professor of media and public affairs at George Washington University, calls this recent phenomenon "ambient journalism," or "when you're constantly plugged in through social media and you're constantly online and engaged in some way." And that - that constant bumping into news and online discord, that constant engagement - over time, it becomes an assault. And, Usher says, besides that aggression of immediacy, a lot of the headlines we consumed this year, particularly about the election, pushed a certain narrative: a nation, and even a world, completely and disastrously divided, perhaps beyond repair. "Lots of crappy, bad things happen every year," she says, "but you aren't told over and over again that this just shows us how bad everything is."

It takes just one-tenth of a second for our brains to begin to recognize emotions conveyed by vocalizations; apparently human brains pay more attention when emotions are embedded in vocalizations rather than in speech. Participants were able to detect vocalizations of happiness (i.e., laughter) more quickly than vocal sounds conveying either anger or sadness. Vocalizations displaying anger, however, are more resonant than those displaying other emotions: both produced ongoing brain activity that lasted longer than either of the other emotions: "listeners engage in sustained monitoring of angry voices, irrespective of the form they take, to grasp the significance of potentially threatening events." More anxious individuals also have a faster and more heightened response to emotional voices in general than people who are less anxious.
