Brain connectivity improves human aesthetic responses to music
Abstract:
1. white matter connectivity between sensory processing areas in the superior temporal gyrus and emotional and social processing areas in the insula and medial prefrontal cortex explains individual differences in reward sensitivity to music.
2. findings provide the first evidence for a neural basis of individual differences in sensory access to the reward system, and suggest that social–emotional communication through the auditory channel may offer an evolutionary basis for music making as an aesthetically rewarding function in humans.
3.carried out by --Using a combination of survey data, behavioral and psychophysiological measures and diffusion tensor imaging,
Conclusion:
Results from diffusion tensor imaging show that white matter connectivity between auditory perceptual regions (pSTG) and regions of the brain important for emo-
tional and social processing (aIns, mPFC) reflect individual differences in the tendency to experience chills from music.
The chills group showed higher volume in tracts between seedr egions in the pSTG and target regions in the aIns and mPFC, es-
pecially on the right side, which survived correction for the multiple comparisons of three different tracts tested on both
hemispheres. Effects are not attributable to gender, ethnicity, IQa nd language differences, years of musical training or personality, as the two groups are matched for these variables .
2.Thus, the present findings may suggest that people who have difficulty in experiencing strong emotional responses
to aesthetic stimuli, such as people with musical anhedonia(Mas-Herrero et al., 2014), may also be susceptible to other
insensitivities or even impairments in emotional and social functioning.
3.The current findings alsoconverge with prior reports that people who are emotionallyempathic have higher white matter integrity in the temporal and frontal lobe regions also traversed by the arcuate and un-cinate fasciculi (Parkinson and Wheatley, 2014).
4.the volume of white matter connectivity was
significantly correlated with a participant’s tendency to experi-
ence chills: the more frequently a person reports experiencing
chills, the larger the volume of white matter connectivity
among these three regions of the brain. The tract volume was
also negatively correlated with mean IBI during peak pleasure
rating
