Language processing is a function more of the left side of the brain than the right side, particularly Broca's area and Wernicke's area, though the roles played by the two sides of the brain in processing different aspects of language are still unclear. Music is also processed by both the left and the right sides of the brain.
According to research, listening to music has been found to affect the mood of an individual. The main factors in whether it will affect that individual positively or negatively are based on the musics tempo and style. In addition, listening to music also increases cognitive functions, creativity, and decreases feelings of fatigue.
Whenever brain activity occurs in a given area these molecules are recruited to the area. Once the concentration of the biologically active molecule, and its radioactive "dye", rises enough, the scanner can detect it. [3] About one second elapses from when brain activity begins to when the activity is detected by the PET device.
Music is able to access many different brain functions that play an integral role in other higher brain functions such as motor control, memory, language, reading and emotion. Research has shown that music can be used as an alternative method to access these functions that may be unavailable through non-musical stimulus due to a disorder.
“In a nutshell, music can activate various parts of the brain associated with emotions and our thought processes. These factors combined give music its mood-boosting powers,” Dr. Conley says.
The term "musical anhedonia" was first used in 2011. It was originally used to describe the selective loss in emotional responses to music following damage to the brain. It has now come to mean, more generally, a selective lack of pleasurable responses to music in individuals with or without brain damage.
The mode of music (major or minor), and the tempo of a song (fast or slow) can invoke joy or sorrow in the listener. [6] In the brain, emotional analysis is carried out by "a common cortical relay, suggesting no direct access to subcortical, limbic structures". [7]
One study found that after researching through studies from the past 50 years, there are more than 500 functions for music. [1] Music is heard by people daily in many parts of the world, and affects people in various ways from emotional regulation to cognitive development, along with providing a means for self-expression.
