“…The phase reset model (Sauseng et al, 2007) claims that the reaction reflects a change in background neural oscillation. This has been demonstrated by original research (Mormann et al, 2005;Rizzuto et al, 2006;Jutras et al, 2013;Woolnough et al, 2022). New evidence .…”

This article is an answer to a report called “What is the evidence on the role of the arts in improving health and well-being?” The authors conclude that the arts have an impact on mental and physical health. Yet, the question of the role of the arts remains unanswered. What is and what is not an art effect? Recently, embodied theory has inspired articles on the perception of art. These articles have not yet received attention in the field of Arts and Health. Scholars in psychosomatic medicine have argued for an approach based on recent work in enactive embodied theory to investigate the connection between the body and the mind. The present article examines how key concepts in this theory relate to art. This leads to a discussion of art in terms of empathy—the relation between the internal state of the artist and the internal state of the beholder. I exemplify with a conceptual framework of musical empathy. Implications for health are addressed.

“…We expect that participants with greater than 30cm coverage will extend the linear trend reported here. Previous studies of cortical phase dynamics, and specifically, TWs at a variety of spatial scales, have illustrated their functional significance (2,3,8,30,(43)(44)(45)(46)(47)(48)(49)(50). The role of the different temporal frequency bands is better understood (51) than spatial frequency, at least to the extent that different temporal frequencies are known to subserve different functions.…”

The dominance of global phase dynamics in human cortex, from delta to gamma

The organization of the phase of electrical activity in the cortex is critical to inter-site communication, but the balance of this communication across macroscopic (>15cm), mesoscopic (1 to 15cm) and microscopic (<1cm) ranges is an open question. Traveling waves in the cortex are spatial phase gradients, such that phase values change smoothly through the cortical sheet over time. Macroscopic cortical traveling waves have been understudied compared to micro- or mesoscopic waves. The spatial frequencies (i.e., the characteristic scales) of cortical waves have been characterized in the grey-matter for micro- and mesoscopic scales of cortex and show decreasing spatial power with increasing spatial frequency. This research, however, has been limited by the size of the measurement array, thus excluding macroscopic traveling waves. Obversely, poor spatial resolution of extra-cranial measurements prevents incontrovertible macroscopic estimates of spatial power via electroencephalogram and magnetoencephalogram. We apply a novel method to estimate the spatial frequency spectrum of phase dynamics in order to quantify the uncertain macroscopic scale. Stereotactic electroencephalogram is utilized to leverage measurements of local-field potentials within the grey matter, while also taking advantage of the sometimes large extent of spatial coverage. Irregular sampling of the cortical sheet is offset by use of linear algebra techniques to empirically estimate the spatial frequency spectrum. We find the spatial power of the phase is highest at the lowest spatial frequencies (longest wavelengths), consistent with the power spectra ranges for micro- and meso-scale dynamics, but here shown up to the size of the measurement array (15-25cm), i.e., approaching the entire extent of cortex. Low spatial frequencies dominate the cortical phase dynamics. This has important functional implications as it means that the phase measured at a single contact in the grey-matter is more strongly a function of global phase organization than local. This result arises across a wide range of temporal frequencies, from the delta band (2Hz) through to the high gamma range (100Hz).
