"Science all but confirms that humans are hard-wired to respond to music. Studies also suggest that someday music may even help patients heal from Parkinson's disease or a stroke. In The Power of Music, Elena Mannes explores how music affects different groups of people and how it could play a role in health care. Mannes tracked the human relationship with music over the course of a life span. She tells NPR's Neal Conan that studies show that infants prefer "consonant intervals, the smooth-sounding ones that sound nice to our Western ears in a chord, as opposed to a jarring combination of notes." In fact, Mannes says the cries of babies just a few weeks old were found to contain some of the basic intervals common to Western music. She also says scientists have found that music stimulates more parts of the brain than any other human function. That's why she sees so much potential in music's power to change the brain and affect the way it works. Mannes says music also has the potential to help people with neurological deficits. "A stroke patient who has lost verbal function - those verbal functions may be stimulated by music," she says. One technique, known as melodic intonation therapy, uses music to coax portions of the brain into taking over for those that are damaged. In some cases, it can help patients regain their ability to speak. And because of how we associate music with memories, Mannes says such techniques could also be helpful for Alzheimer's patients. Less recently, archaeologists have discovered ancient flutes - one of which is presumed to be the oldest musical instrument in the world - that play a scale similar to the modern Western scale. "And remarkably," Mannes says, "this flute, when played, produces these amazingly pure tones." It's a significant discovery because it adds to the argument that musical ability and interest were present early in human history."

"This week, Adele won a number of Grammys, including best pop solo performance for her song "Someone Like You." Inspired by this Wall Street Journal article on how music conveys emotion, we talked to McGill professor Dan Levitin about what makes music, and in particular Adele's "Someone Like You", so emotionally powerful. "

"What if you could predict a hit? It's a music industry dream (or nightmare depending on how you look at it.) New research from Emory University suggests that the answers might lie in our brains. Dr. Gregory Berns and his team have discovered that teens have tell-tale brain responses when listening to hit songs, and that could help predict a song's commercial success. He explains to Jim and Greg that the discovery was an accident. After conducting MRI studies on teens listening to MySpace music, he noted that one of the tracks, One Republic's "Apologize" became an American Idol hit years later. Strong activity in two brain regions could predict hits about 1/3 of the time. Weak activity was even better at predicting non-hits. And brain responses in those regions were better predictors of song success than whether the participants said they liked or disliked any given song. Jim and Greg aren't teens, but wonder if their work could be made easier with MRI technology. "

"FOR a brief, heady period in the history of autism spectrum diagnosis, in the late '90s, I had Asperger syndrome. There's an educational video from that time, called "Understanding Asperger's," in which I appear. I am the affected 20-year-old in the wannabe-hipster vintage polo shirt talking about how keen his understanding of literature is and how misunderstood he was in fifth grade. The film was a research project directed by my mother, a psychology professor and Asperger specialist, and another expert in her department. It presents me as a young man living a full, meaningful life, despite his mental abnormality. "Understanding Asperger's" was no act of fraud. Both my mother and her colleague believed I met the diagnostic criteria laid out in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. The manual, still the authoritative text for American therapists, hospitals and insurers, listed the symptoms exhibited by people with Asperger disorder, and, when I was 17, I was judged to fit the bill. I exhibited a "qualified impairment in social interaction," specifically "failure to develop peer relationships appropriate to developmental level" (I had few friends) and a "lack of spontaneous seeking to share enjoyment, interests, or achievements with other people" (I spent a lot of time by myself in my room reading novels and listening to music, and when I did hang out with other kids I often tried to speak like an E. M. Forster narrator, annoying them). I exhibited an "encompassing preoccupation with one or more stereotyped and restricted patterns of interest that is abnormal either in intensity or focus" (I memorized poems and spent a lot of time playing the guitar and writing terrible poems and novels). The general idea with a psychological diagnosis is that it applies when the tendencies involved inhibit a person's ability to experience a happy, normal life. And in my c

"Here's a little ditty that catalogs and musically explains a useful list of cognitive biases uncovered by behavioral psychologists. It was created by Bradley Wray, a high school teacher in Maryland, as a study aid for students preparing for their AP Psychology exam. How are you biased? Let Bradley Wray count the ways."

"Acousticians have been designing concert halls for more than a century, but Dr. Kyriakakis does something different. He shapes the sound of music to conform to the space in which it is played. The goal is what Dr. Kyriakakis calls the "ground truth" - to replicate the original in every respect. "We remove the room," he said, "so the ground truth can be delivered." Dr. Kyriakakis, an electrical engineer at U.S.C. and the founder and chief technical officer of Audyssey Laboratories, a Los Angeles-based audio firm, could not achieve his results without modern sound filters and digital microprocessors. But the basis of his technique is rooted in the science of psychoacoustics, the study of sound perception by the human auditory system. "It's about the human ear and the human brain, and understanding how the human ear perceives sound," Dr. Kyriakakis said. Psychoacoustics has become an invaluable tool in designing hearing aids and cochlear implants, and in the study of hearing generally. "Psychoacoustics is fundamental," said Andrew J. Oxenham, a psychologist and hearing expert at the University of Minnesota. "You need to know how the normally functioning auditory system works - how sound relates to human perception." "
