connectivity

Recent studies conducted by the doctors have proved that poor connectivity in your brain makes you hate music. This symptom is a threat to Anhedonia. Lack of brain connectivity also affects other functions in human body.

Studies say that people who cannot tolerate music at all may have reduced connectivity between two regions in the brain which is closely linked to sound processing. This symptom has been detected by a new study.

Doctors say that they may have a condition called specific musical Anhedonia, which affects three-to-five percent of the entire population of the world. Though the percent is small, still it’s a dangerous symptom to take care of.

Researchers at the University of Barcelona in Spain and the Montreal Neurological Institute (MNI) and Hospital of McGill University in Canada in a joint study have found out that people with this condition showed reduced functional connectivity between cortical regions which is highly responsible for processing sound and sub-cortical regions related to the brain.

Researchers have recruited 45 healthy participants who completed a questionnaire measuring their level of sensitivity to music. They divided them into three main groups of sensitivity based on their responses. The result was tremendously dangerous.

The test participants were made to listen to music pieces inside an fMRI machine. They were also made to provide pleasure ratings in real-time.

Using the fMRI data, researchers have found that while listening to music, specific musical Anhedonia provided a reduction in the activity of the Nucleus Accumbens, a key sub-cortical structure of the brain network.

The reduction percentage was merely not related to the general improper functioning of the Nucleus Accumbens itself, but this region was activated when they won money in the gambling task.

Specific musical Anhedonia, however, has shown reduced functional connectivity between sub-cortical regions which is closely associated with auditory processing and the Nucleus Accumbens.

A study was also conducted with the children. The studies of children with autism spectrum disorder have shown their inability to experience the human voice. This agreeably may be explained by a reduced coupling between the bilateral posterior superior temporal sulcus and distributed nodes of the brain responsive system, including the Nucleus Accumbens.

This latest research strengthens the significance of neural connectivity in the brain response of human beings. The percent of this symptom is found in a lesser number of people but is dangerously harmful.
