According to the latest study, neural circuits that are linked to the creativity centers of the brain gets altered when the artists try to express their emotions. The research conducted by University of California, San Francisco, suggests that it is not possible to explain the creativity entirely in terms of its activation or deactivation with regards to brain regions. Instead, the researchers said that when creativity is linked to conveying specific emotions, the nature of it influences which part of the creativity of brain will get activated and what to end. The lead author, Charles Limb, said that the brain and its emotional matters are not just binary situations according to which it will work. Instead, there are different versions of these emotional states as greater degree of emotion or lower degree, reported Financial Express. Malinda McPherson, the lead author of the study, revealed that the deactivation of DLPFC was higher when the jazz musicians, while playing keyboard during their fMRI scan improvised melodies to convey positive emotions.

"The bottom line is that emotion matters," said senior author Charles Limb, MD, an avid jazz musician and physician-researcher at UC San Francisco. "It isn't just a binary situation in which your brain works one way when you're being creative and another way when you're not. Instead, there are greater and lesser degrees of creative states, and different versions of these states. And emotion plays a crucially important role in these differences."

For every musician, any brain activity that was generated during the times when they passively viewed the images, including their emotional response, were removed from the ones provoked during musical performances. This helped the researchers to determine which parts of brain activity were strongly influenced by emotions while creating improvisations. "There is more deactivation of the DLPFC during happy improvisations, perhaps indicating that people are getting into more of a 'groove' or 'zone,' but during sad improvisations there's more recruitment of areas of the brain related to reward," said Malinda McPherson, a classical violist who led the study, said Business Standard
