An independent study by researchers at Dartmouth College in Hanover, New Hampshire, identified the postromedial prefrontal cortex of the brain as the area that recalls melodies. This is the section of the brain that remembers music and is able to distinguish a sour or wrong note in a familiar tune. Peter Janata of Dartmouth's Center for cognitive Neuroscience explored the mind's, memory for tune by studying the brains of eight musicians as they listened to original music. Scientist at Dartmouth used magnetic resonance imaging to detect the part of the brain active in response to specific stimuli. They identified the ability to recognize music is contained in an area centrally located area just behind the forehead. Peter Janta was quoted as saying "that part of the brain also plays a key role in learning and in the response and control of emotions." A study published in the Journal of Science indicated that eight people who had studied music for at least 12 years listened to the music and were asked to pick out specific tones and to detect notes played by a flute-like instrument instead of a clarinet which had dominated the music. A functional MRI tracked which parts of the brain were active as the musicians performed the task. Researchers reported that the brains of each of the subjects tracked the sounds in a slightly different way each time the music was played. This may be the reason that music may prompt different emotions and responses in individuals. The brain appears have evolved to appreciate and remember music. Pleasant sounds were an important part of the human mind and experience from the earliest times. The research did not indicate that music recognition was necessary for survival yet it is something we crave. It would appear instinctive that birds singing, the sound of waterfalls and a light breeze would indicate a tranquil safe environment. It would also seem logical that singing to a baby or tribe rituals had a profound and lasting influence upon the individual and society. Think about the type of music your listen to and how you respond to your environment and those around you. It is easy to recall a variety of experiences and emotions simply by listening to a tune. Hemi-Sync MetaMusic is designed to combine sound frequencies with music to entrain brain waves. Brain wave synchronization can and will effect emotional responses, learning, memory and attitude. Many Hemi-sync titles are directly attributed to enhanced learning and memory. To learn more about Metamusic click here.
