It has been found that the human mind shows different responses to happy and sad music. The networks that lit up in the brain under MRI scans were radically apart in their loci.
Emotional circuits in the brain show various effects upon hearing sad and upbeat music. The creativity centers in the human mind are affected differently by different responses among jazz musicians.

A neural circuit associated with creativity – which is the highest value – was shown to react in accordance with the type of music which entered the ear. However, it was not as simple as an on-and-off switch. Creative acts light up different neuronal centers in the brain.
Especially, emotional expression was the first thing to show up on the screen when the neuro-images were being processed. Emotions seem to matter more than we thought.
They are not wishy washy entities at all. And the activation or inactivation of creativity were not the only thing involved in the registration of stimuli in the brain. Emotions play a vital role in the whole plan of the brain whereby mankind has progressed to such a dominant position on face of the planet.
The research appeared in a journal. Most of the experiments were carried out in laboratory settings. The professor who conducted the studies was an accomplished jazz saxophonist and often inserted cochlear implants to restore hearing.
Previous research by this man included MRI scans that provided important clues as to musical freestyle methods, rapper’s staccato delivery schemes and caricatures. The unfolding of the implicit order in these random creative acts deactivate a region of the brain known as the DLPFC.
This is the dorsolateral prefrontal cortex. It’s involved in both planning and overseeing behavior. This turning off of the DLPFC causes the person to enter a flow state which is the ideal condition for creativity to flourish.
In the study, it was found that DLPFC inactivation was far more potent when the jazz musicians used extreme improvisational strategies. As they made things along the way and on the spot, the brain areas responsible for creativity lit up. And when these musicians expressed emotions associated with a smiling woman these bubbly and bright creativity centers were activated.
Then when they showed sad moods in their music as based on a woman who was crying these centers went dark on the screen. The negative image musical moods that got expressed activated the reward system in the brain. And they also jump-started the DLPFC centers.
"The notion that we can study complex creativity in artists and musicians from a neuroscientific perspective is an audacious one, but it's one that we're increasingly comfortable with," said senior author Charles Limb, MD.
"Not that we're going to answer all the questions, but that we have the right to ask them and to design experiments that try to shed some light on this fascinating human process."
