Music and lyrics: How the brain splits songs

Your favourite song comes on the radio. You hum the tune; the lyrics remind you of someone you know. Is your brain processing the words and music separately or as one? It’s a hotly debated question that may finally have an answer.

Researchers find how brain hears the sound of silence

A team of University of Oregon researchers have isolated an independent processing channel of synapses inside the brain’s auditory cortex that deals specifically with shutting off sound processing at appropriate times. Such regulation is vital for hearing and for understanding speech.

All languages are created in the same brain areas

Be it American Sign Language or English, language is created in the same areas of the brain, claim scientists. Karen Emmorey, a professor of speech language at San Diego State University, suggests language is universal and doesn’t depend on whether people use their voices or their hands to talk.

Tip-of-the-Tongue Moments Explained

It’s one of the most frustrating feelings: You know the word exists, and you know what it means, but you just can’t spit it out. New research suggests the forgetfulness may have to do with how frequently we use certain words. The findings could help scientists understand more about how the brain organizes and remembers language.

Same Brain Spots Handle Sign Language and Speaking

Language is created in the same areas of the brain, regardless of whether a person speaks English or uses American Sign Language to communicate, new research found. The discovery suggests that something about language is universal and doesn’t depend on whether people use their voices or their hands to talk.

Research Lays The Foundation For Improving Human Speech

Scientists at Duke University Medical Center have identified neurons in the songbird brain that convey the auditory feedback needed to learn a song. Their research lays the foundation for improving human speech, for example, in people whose auditory nerves are damaged and who must learn to speak without the benefit of hearing their own voices.

Why can’t chimps speak? Study links evolution of single gene to human capacity for language

If humans are genetically related to chimps, why did our brains develop the innate ability for language and speech while theirs did not? Scientists suspect that part of the answer to the mystery lies in a gene called FOXP2. When mutated, FOXP2 can disrupt speech and language in humans. Now, a UCLA–Emory University study reveals major differences between how the human and chimp versions of FOXP2 work, perhaps explaining why language is unique to humans.

Words, Gestures Are Translated by Same Brain Regions, Says New Research: Findings May Further Our Understanding of How Language Evolved

Your ability to make sense of Groucho’s words and Harpo’s pantomimes in an old Marx Brothers movie takes place in the same regions of your brain, says new research funded by the National Institute on Deafness and Other Communication Disorders (NIDCD), one of the National Institutes of Health.

Study Sheds New Light On The Nature Of Broca’s Area In The Brain

A study by researchers at the University of California, San Diego School of Medicine reports a significant breakthrough in explaining gaps in scientists’ understanding of human brain function. The study – which provides a picture of language processing in the brain with unprecedented clarity – is published in the October 16 issue of the journal Science.

Brains benefit from multilingualism

For a considerable time already there has been discussion within scientific circles about whether knowing and using multiple languages could possibly have positive effects on the human brain and thinking. There have been a number of international studies on the subject, which indicate that the ability to use more than one language brings an individual a considerable advantage. The report of the research team appointed by the European Commission, ”The Contribution of Multilingualism to Creativity”, presents the first known macro analysis based on the available evidence, which has been conducted by searching through several studies and giving particular attention on recent research on the brain.

Figures of speech — understanding idioms requires both sides of the brain

Is it better to treat someone with kid gloves or to treat them carefully? Researchers in Italy have investigated how the brain recognises that the first phrase means the same as the second. Publishing in the open access journal BMC Neuroscience, the researchers suggest that we use both hemispheres to understand idioms.

Familiar and newly learned words are processed by the same neural networks in the brain

Our vocabulary continues to grow and expand even in adulthood. Just ten years ago, the word ‘blog’ did not yet exist – and now we no longer remember when we heard this word for the first time or when we learned its meaning. At some stage new words become just as familiar to us as words we have learned earlier. One of the areas of interest in the Academy of Finland’s Neuroscience Research Programme (NEURO) is how the process of learning new words is reflected in the function of the brain.

Study shows bilinguals are unable to ‘turn off’ a language completely

According to a recent study published in Psychological Science, a journal of the Association for Psychological Science, it appears humans are not actually capable of “turning off” another language entirely. Psychologists Eva Van Assche, Wouter Duyck, Robert Hartsuiker and Kevin Diependaele from Ghent University found that knowledge of a second language actually has a continuous impact on native-language reading.
