Happiness Associated with Noh-masks Modulates the Mesolimbic Reward System: an Fmri Study Based on Neuroaesthetics
نویسنده
چکیده
We report a brain imaging study with fMRI in which participants were scanned while watching Noh masks with face expressions rated as happy. Among seventy standard masks previously rated by the participants, we selected the six happiest masks and six neutral masks to explore the neural correlates of happiness associated with Noh masks. Results based on region of interest (ROI) analysis indicated activations of nucleus accumbens (Nacc) while viewing happy masks. We suggest that as the Nacc activation increased, happiness tended to increase possibly due to enhanced dopaminergic activity in the Nacc associated with the reward by observing smiling masks.

Something funny happened to reward.
The human reward system has been shown to be activated by a wide range of reinforcers, including food, money, sex, drugs, and beauty. Now, a recent fMRI study has found mesolimbic reward activation associated with humorous cartoons, providing a neurobiological link between theories of humour and hedonic processes in the brain.
متن کاملMesolimbic functional magnetic resonance imaging activations during reward anticipation correlate with reward-related ventral striatal dopamine release.
The dopaminergic mechanisms that control reward-motivated behavior are the subject of intense study, but it is yet unclear how, in humans, neural activity in mesolimbic reward-circuitry and its functional neuroimaging correlates are related to dopamine release. To address this question, we obtained functional magnetic resonance imaging (fMRI) measures of reward-related neural activity and [(11)...
متن کاملNeural correlates of specific musical anhedonia.
Although music is ubiquitous in human societies, there are some people for whom music holds no reward value despite normal perceptual ability and preserved reward-related responses in other domains. The study of these individuals with specific musical anhedonia may be crucial to understand better the neural correlates underlying musical reward. Previous neuroimaging studies have shown that musi...
متن کاملLower neighborhood quality in adolescence predicts higher mesolimbic sensitivity to reward anticipation in adulthood
Life history theory suggests that adult reward sensitivity should be best explained by childhood, but not current, socioeconomic conditions. In this functional magnetic resonance imaging (fMRI) study, 83 participants from a larger longitudinal sample completed the monetary incentive delay (MID) task in adulthood (∼25 years old). Parent-reports of neighborhood quality and parental SES were colle...
متن کاملBrain Activity Map Extraction of Neuromyelitis Optica Patients Using Resting-State fMRI Data Based on Amplitude of Low Frequency Fluctuations and Regional Homogeneity Analysis
Introduction: Neuromyelitis Optica (NMO) is a rare inflammatory disease of the central nervous system which generally affecting the spinal cord and optic nerve. Damage to the optic nerve can result in the patient's dim vision or even blindness, while the spinal cord damage may lead to sensory and motor paralysis and the weakness of the lower limbs in the patient. Magnetic Reson...
