Brain Anatomy pleasant music
There are two neuroanatomical systems involved in the pleasure that music produces on the one hand cognitive and motor systems (cerebral cortex) and, second, the emotional brain, the limbic system. At the level of the cerebral cortex highlight three anatomical regions: orbitofrontal cortex, superior temporal cortex and the anterior cingulate.
Dopamine is released at the height of the melody, is that moment when a chill through our bodies. It has been shown also that a few seconds before there is a release of dopamine associated with anticipation.
At the peak of pleasure is activated limbic system area called the nucleus accumbens is literally flooded with dopamine. This area is responsible for the euphoria . The nucleus accumbens plays an important role in reward, laughter, pleasure and addiction. It is the anatomical site in which highly addictive drugs (cocaine, amphetamine …) cause an increased release of dopamine.
Brain Anatomy unpleasant music
But, what happens when it comes to music that is unpleasant? Instead of activating the nucleus accumbens is activated amygdala and parahippocampal gyrus. This anatomical region is also involved in the music of suspense, so patients who have the injured area are unable to recognize danger signals from the music.
In short, the pleasure we should be music to the release of dopamine at the nucleus accumbens, whereas when we find unpleasant music that activates the area is the amygdala, which is also involved in music recognition related to the danger or suspense.
