The indifference to music is due to brain disconnections.
The indifference to music is due to brain disconnections between the regions that record the sounds and those that generate positive emotions. It affects healthy people who represent between 3% and 5% of the population. These people can sort music and even rejoice to make money playing poker. A discovery that will help treat better diseases like Alzheimer's, depression or drug addiction. Money, sex, drugs and rock and roll stimulate the release of dopamine in different areas of the brain, which causes a sensation of pleasure. This circuit is called a reward system. The existence of anhedonia has long been known, which is the inability of some people to experience positive emotions. Anxiety is one of the symptoms of depression, although it may also be present in some cases of dementia such as Alzheimer's or schizoid personality disorder.
Musical anhedonia is a specific manifestation of this inability. The people who suffer from it can be totally healthy from a medical and emotional point of view, but listening to music leaves them indifferent. Musical anhedonia affects between 3% and 5% of the population.
According to a study carried out in 2013, the musical anhedonia is due to the absence of brain connections between the zone that manages the sounds and the reward system, although both regions function normally. A second study published in 2014 by researchers, among others, of the University of Barcelona, which we reported in another article, deepened the knowledge of anhedonia. Not only did he observe the participants' brains, he also recorded their psychological constants to measure the intensity of their emotions. In this way he discovered that people suffering from musical anhedonia can even categorize the music, even if they do not record any emotion when listening to it. And he concluded that the brain circuits related to the pleasure of listening to music are specific, and different, for example, from pleasure related to other human activities. Now, a third study published in PNAS, reported in a statement, sheds new light on anhedonia. It gathered 45 volunteers, divided between hyperhedonists, anhedonic and normal people in terms of their emotions, in order to deepen the knowledge of anhedonia.
