Humans have a special ability to learn songs and change them over time—a skill that is useful in treating neurological problems and may help support overall brain health. Researcher Aniruddh D.
Patel explains. Birds do it. Bees do it. Even itty-bitty fruit flies do it. They sing, and often quite beautifully. Just think of the intricate and mournful song of a loon heard on the lake at sundown. Human song connects us, not just to each other, but to other species.
But there are key differences in the way humans and other animals sing, and those differences point to the unusually important role that sound plays in human brain function. Aniruddh D. For most creatures, their song changes very little over time.
Except for a few species of birds, such as parrots and hummingbirds, and certain sea mammals, such as beluga whales, the ability to learn songs is uniquely human. Humans are primates, with the same forward-facing eyes and great depth and color perception that helps all primates navigate their environments.
But the human brain differs from the brains of other primates because of the prominence of our temporal lobes—areas of the brain around the temples that are involved in auditory processing. Our heightened ability to analyze sounds may have been adaptive. He connects this group identification with the way accents tell us what region or country a G. Traeger - Klein Justus comes from today.
They are a strong identifier of early community. The fact that sound is such a powerful part of human brain functioning has opened up rich areas of research.
One area is the use of song to improve brain function for people with neurological issues. Nonfluent Aphasia. In the s, a new therapy sought to harness the power of song to help patients with nonfluent aphasia improve their speech abilities. In an ongoing study at Harvard Medical School led by Gottfried Schlaug, MIT is being compared to speech repetition therapy, a conventional treatment in which patients repeat phrases to the therapist without the melodic component.
Preliminary results have shown that both groups improved in speech ability, but in the MIT group there was an improvement of percent, compared to an improvement of percent in the speech repetition therapy group. Brain imaging confirmed what the researchers were observing. The researchers also looked at connections between different regions in the brain to see if those connections had been changed or strengthened by the Melodic Intonation Therapy.
They focused on one long-distance connection from the front to the back of the brain that is important for speech and song called the arcuate fasciculus. If you introduce a wrong note into the song, they will startle, which is evidence they know the details of that melody. The music we remember from our youth often reawakens memories of where we were in our lives, who we were with, what we were like, what we were going through. But why is musical memory preserved in dementia?
Again, studies using brain imaging can help explain. Studies by Petr Janata and colleagues at UC Davis found that music that had the qualities of being familiar, pleasing, and evocative of autobiographical memories was processed predominantly in the dorsomedial prefrontal cortex. Could regular singing have a lasting impact on brain function? The research about the effects of song on people with brain conditions raises hope for more far-reaching Martin Eckert - Rocket/Freudental - Wir Arbeiten Durch. To address that question, Schlaug and his team have done MRIs of older healthy adults, dividing them into a group of singers and a group of non-singers.
The group of singers showed greater connections between areas of the brain than the non-musician group, with the strongest difference on the left side. These findings suggest new research possibilities, Patel says. Another research area that Patel is heading up at his lab at Tufts University is studying the relationship between singing and prediction—the ability to anticipate what comes next.
A longtime topic of research in music cognition, prediction has also recently become a growing focus of research in language processing. In his book Sweet Anticipation: Music and the Psychology of Expectation, David Huron shows how common musical devices such as syncopation, cadence, meter, tonality, and climax exploit basic psychological mechanisms of expectation.
For example, successfully anticipating the outcome of a particular musical phrase can trigger positive feelings—even more Amante De Abril Y Mayo - Concha Piquer* - Album De Oro if the gratifying outcome is delayed by a slower tempo or another compositional technique.
The ability to predict what comes next is also central to the way we experience language. That can help in understanding people in noisy Native Dance - Peo Alfonsi, Salvatore Maiore - Alma (SACD, Album) or where things are slightly ambiguous.
Patel and his team wanted to know: do music and language share mechanisms for prediction? But in fact, there is a lot of research that indicates there is much more overlap than we had thought. An example of a sentence pair is:. The second does not, as people vary in the word they use to complete the thought. The first melody leads to a strong prediction. Since it ends with an implied authentic cadence, most people sing the tonic D as a continuation of this melody.
Although the second melody is identical to the first in length, rhythm, melodic contour, musical key and number of notes, people vary widely in the note that they sing as a continuation.
The idea is to compare patterns of brain activity as research subjects process predictions for sentences versus melodies to see how these patterns are similar or different.
In another study, Patel plans to examine whether musical training enhances linguistic prediction abilities. This could have implications for language skills for young and old. The OPERA hypothesis suggests that because music and speech share some cognitive processing mechanisms in the brain, and music places.
