For behavioral data, Pearson r correlations were performed to explore the link between the number of chills reported and BMRQ scores, sex, age, and years of musical practice. Dissociation between musical and monetary reward responses in specific musical anhedonia. They have a higher volume of fibers that connect their auditory cortex to the areas associated with emotional processing, which means the two areas communicate better. Neuroscientists use EEG as a novel technique to map activity in the reward system of the brain in people who experience pleasurable “chills” from listening to music. Dopamine modulates the reward experiences elicited by music. 30, 7078–7087. Panksepp found that chills and … – only about half of people get chills when listening to music. (A) Comparison of power spectral density (μV2/Hz) values in the theta and alpha frequency range for each condition (LP, low pleasure; HP, high pleasure; Chills) in the prefrontal, frontal, central, and temporal ROIs (*p < 0.05, **p < 0.01, errors bars represent SEM). The auditory cortex localized in the superior temporal gyrus is connected to the OFC, and these two structures exchange information during music processing (Brown et al., 2004). Humans are drawn towards music perceived as pleasant – such as the phenomenon of chills, where music activates the same dopamine releasing reward systems involved in eating, sex, and recreational drug use (Salimpoor, Benovoy, Larcher, Dagher, & Zatorre, 2010). Neurosci. Every epoch with visually detectable artifacts was removed from the analysis. The results are published in Frontiers in Neuroscience. The extracts for each participant were not restricted to only positive or negative valence, and this should have affected the asymmetry results. Affect. (2015). Considering these facts in addition to the gradual increase of theta activity in the prefrontal ROI when the emotional ratings increased, we can reasonably hypothesize that the increased power of the theta activity is linked to the intensity of the felt pleasure. Intra- and inter-brain synchronization during musical improvisation on the guitar. Those who do, are considered to have an “enhanced ability to experience intense emotions”. The neutral extracts were selected from a list of musical extracts that had been rated for attractiveness/averseness and arousal by an independent sample of 12 people before the experiment. The results are published in Frontiers in Neuroscience. Sci. Most of the participants reported difficulty distinguishing between the neutral and low pleasure emotional states and usually used only one of the two conditions when reporting low emotional state. Reward dependent invigoration relates to theta oscillations and is predicted by dopaminergic midbrain integrity in healthy elderly. For this reason, some participants did not report enough chills and were therefore excluded from EEG analysis. This is a response that indicates greater connectivity in the cerebrum. Several structures were identified using fMRI, such as the amygdala, prefrontal cortex, or even auditory cortex, which were linked with arousal changes while listening to music (Daly et al., 2019).

To refer to these people as “having unique brains” would imply that they do not fall within the normal distribution of the population. However, we observed increased activation of both the bilateral insula and the left and right temporal gyri with higher emotional ratings. N. Y. Acad. (2009).

(2011). I. For asymmetry analysis, the comparison of each condition did not show a significant group effect either for alpha frontal asymmetry [F(2.15) = 0.32; p = 0.75] or for alpha prefrontal asymmetry [F(2.15) = 0.06; p = 0.94] (Figure 4). The sample for this study consisted of 18 healthy volunteers (11 women, 7 men) with a mean age of 39.7 years (SD 18.3, range 18–73). These differences account for the unique reactions that they experience (1). NeuroscienceNews, 23 February 2017. (2018) was performed by calculating the beta to alpha ratio according to the following equation: To identify the source that generates the activities observed on the scalp, it is possible to apply source localization analyses that convert EEGs to a real neuroimaging modality (Michel and Brunet, 2019). (2013). HD-EEG results showed an increase of theta activity in the prefrontal cortex when arousal and emotional ratings increased, which are associated with orbitofrontal cortex activation localized using source localization algorithms.

Previously, research has shown that musical chills occur in two phases: the anticipation before peak-chill as the music is building and the pleasure is growing, which is followed by a second peak pleasure phase. 2017-884 of May 2017) on non-invasive protocols involving healthy humans. Neurosci. doi: 10.1525/mp.2013.31.2.118, Mas-Herrero, E., Zatorre, R. J., Rodriguez-Fornells, A., and Marco-Pallarés, J. Fifty-eight did not fulfill the eligibility criteria (2 scored lower than 65 for the BRMQ, 3 were not exclusively right-handed, 9 did not provide enough chill-inducing extracts, 36 did not respond after their initial request for information/did not send back questionnaires, for 7 we could not program an appointment, and 1 had a haircut incompatible with EEG recording). doi: 10.1097/WNR.0b013e32833774de, Lindenberger, U., Li, S.-C., Gruber, W., and Müller, V. (2009). Ten participants in this sample were amateur musicians (mean of 20.2 years of practice, SD 13.37, range 10–55). It has also been suggested that theta oscillations play a role in the synchronization of temporal and prefrontal structures during musical emotional processing (Lewis, 2005). Neuroscientists based in France have now used EEG to link chills to multiple brain regions involved in activating reward and pleasure systems. This study was supported by a grant from the University Hospital of Besançon (Appel à Projet Interne CHU – APICHU no. The phenomenon of pleasure associated with chills is composed of two phases, an anticipation phase before the chill when the pleasure is growing, with a specific dopamine release in the dorsal striatum (caudate), and a peak pleasure phase with a dopaminergic release in the ventral striatum (nucleus accumbens) (Salimpoor et al., 2011). I have no Septum pallucidum and wonder if this is why I may experience this. 67, 219–233. Because group emotional dynamics is a central concern of social neurosciences, the study of emotion in natural/ecological conditions is gaining interest. You can cancel your subscription any time. U.S.A. 116, 3793–3798. About half of people get chills when listening to music. 40, 209–215. (2019) demonstrated that dopaminergic releases were not only the consequence but actually one of the causes of the felt emotional pleasure. But why exactly does this happen? Neurosci. We hypothesized that the climax of an emotional increase—related to the activation of the approach dimension relative to positive/rewarding stimulation (Omigie et al., 2015)—from neutral to chills should gradually activate the approach dimension, resulting in increased alpha asymmetry. Table 1. doi: 10.1097/00001756-199703030-00044, Chabin, T., Tio, G., Comte, A., Joucla, C., Gabriel, D., and Pazart, L. (2020). At this point, we are not able to explain the stronger effect of theta decrease in the right compared with the left central ROI, even though—as for the prefrontal areas—the same trends were found in both left and right ROIs.

(2018), is likely to be a signature of music liking, and these findings seem to be consistent with ours. doi: 10.1016/j.brat.2017.02.002, Menon, V., and Levitin, D. J. We considered that such a restriction was not in line with our perspectives and would have reflected the cerebral activity relative to only positively or negatively valenced pleasurable musical chills. Proc. The participants rated their overall enjoyment of the experiment at a mean of 7.9 (SD 0.9, range 5–9) on the 10-point Likert scale. There were no effects for the LT ROI [F(2.15) = 0.13; p = 0.87]. Electroencephalographic dynamics of musical emotion perception revealed by independent spectral components. (2014). Source localization revealed a positive link between increased emotional rating and intensity of activation of the medial orbito-frontal cortex [F(2.15) = 17.4; p < 1.10–5], the bilateral insula [F(2.15) = 21.63; p < 1.10–6], the supplementary motor area [F(2.15) = 27.3; p < 1.10–7], and the left and right superior temporal gyri [LSTG: F(2.15) = 17.76, p < 0.00001; RSTG: F(2.15) = 22.05, p < 1.10–6]. doi: 10.1111/j.1469-8986.2007.00497.x, Sänger, J., Müller, V., and Lindenberger, U. The use of mobile wireless EEG could provide the possibility of studying cerebral activity during peak emotion of musical chills in ecological/natural conditions, especially because it can be used in hyperscanning paradigms with several participants simultaneously (Lindenberger et al., 2009; Müller et al., 2013, 2018; Sänger et al., 2013; Acquadro et al., 2016).
