“…We recorded rs-EEG data for each participant for six minutes. The acquisition duration is in line with previous rs-EEG studies ( Babiloni et al., 2023 ; Lapomarda, Valer, Job, & Grecucci, 2022 ; Sun et al., 2019 ). In addition, because opening and closing the eyes reflect different resting states ( Barry, Clarke, Johnstone, Magee, & Rushby, 2007 ), we included both opened and closed eyes to detect an entire resting state.…”

“…Meanwhile, we found a similar scale-free effect at the delta band. Although few studies reported the association between topological deviations in the delta band and emotions, delta frequency has been shown to play an important role in emotion regulation ( Jiang et al., 2022 ; Lapomarda et al., 2022 ). Additionally, similar emotional profiles were associated with similar delta-band activities over the prefrontal and temporoparietal regions ( Hu, Wang, & Zhang, 2022 ).…”

BackgroundIncreasing research has examined the factors related to smartphone use disorder. However, limited research has explored its neural basis.AimsWe aimed to examine the relationship between the topology of the resting-state electroencephalography (rs-EEG) brain network and smartphone use disorder using minimum spanning tree analysis. Furthermore, we examined how negative emotions mediate this relationship.MethodsThis study included 113 young, healthy adults (mean age = 20.87 years, 46.9% males).ResultsThe results showed that the alpha- and delta-band kappas and delta-band leaf fraction were positively correlated with smartphone use disorder. In contrast, the alpha-band diameter was negatively correlated with smartphone use disorder. Negative emotions fully mediated the relationship between alpha-band kappa and alpha-band diameter and smartphone use disorder. Furthermore, negative emotions partially mediated the relationship between delta-band kappa and smartphone use disorder. The findings suggest that excessive scale-free alpha- and delta-band brain networks contribute to the emergence of smartphone use disorder. In addition, the findings also demonstrate that negative emotions and smartphone use disorder share the same neural basis. Negative emotions play a mediating role in the association between topological deviations and smartphone use disorder.DiscussionTo the best of our knowledge, this is the first study to examine the neural basis of smartphone use disorder from the perspective of the topology of the rs-EEG brain network. Therefore, neuromodulation may be a potential intervention for smartphone use disorder.

“…For our study, we selected 3 out of 21 subjects in our dataset based on similarities in EEG patterns during initial EEG channel visualizations, reducing intersubject variability; 25 out of 31 EEG channels for each subject were used and we focused on the delta, theta and alpha bands for their role in emotional processing, meditation/relaxed physical states and music cognition and emotion, respectively 60,[62][63][64] .…”

Music's manifold emotions for mental well-being: a topological approach

Music, an intrinsic part of human culture, has long been recognized for its ability to evoke emotions, memories and physiological responses. From the rhythmic beats that make us dance to the soothing melodies that provide solace in times of distress, music's impact on the human psyche is undeniable. Timely, in the wake of the COVID-19 pandemic, the world has witnessed a subsequent and equally concerning mental health "pandemic.” As societies grapple with the repercussions of prolonged isolation, economic downturns, and the collective trauma of a global health emergency, the search for therapeutic interventions has never been more pressing. Among the myriad of potential solutions, one timeless human experience stands out: the power of music. Our study aims to understand how music’s benefits for well-being can be harnessed to combat the rising levels of neurodegenerative diseases and depression. By exploring the neural manifolds and latent neural dynamics of music listening and emotional experience, we aim to uncover the therapeutic potential of music through topology. Our findings not only shed light on music’s role in mental well-being through emotional synchrony across subjects, but also offer hope in times of crisis. Alongside shared neural dynamics across subjects, we also find one subject in which a major difference in emotional experience leads to a drastically different manifold shape, clustering and coloring. These results are the first to pain music listening, emotional experience and well-being in a topological light. We see our results positioned as a backdrop for future research in computational neuroscience on music and well-being, our study being the first to approach mental well-being and music listening with topology. We also outline next steps that would extend our preliminary results immediately to neurodegenerative diseases, depression and more. In a world where mental health issues are on the rise, this topological approach to music and well-being can provide deeper understanding to music therapy’s non-invasive, accessible and enjoyable avenue for improving the well-being of countless individuals; by accounting for inter-subject variability with topologically-inspired computational neuroscience, we can finally put a name to how music helps heal.

“…Beta rhythm is also generally related to high-level cognitive processes and attention focusing, and high stress causes increased amplitudes in this band. The low-frequency Delta and Theta bands are often seen as markers of the internal concentration of attention when processing information and of the emotional regulation when perceiving various emotion-causing stimuli [ 47 , 48 ]. Therefore, in our experimental study we explore and interpret the EEG signals in each band and relate them to the other variables considered in the study.…”

Nature in the Heart and Mind of the Beholder: Psycho-Emotional and EEG Differences in Perception of Virtual Nature Due to Gender

Natural environment experiences in virtual reality (VR) can be a feasible option for people unable to connect with real nature. Existing research mostly focuses on health and emotional advantages of the “virtual nature” therapy, but studies of its neuropsychological effects related to visual perception are rare. In our experiment, 20 subjects watched nature-related video content in VR headsets (3D condition) and on a computer screen (2D condition). In addition to the gender factor, we considered the individual Environmental Identity Index (EID) and collected the self-assessment of the emotional state per the components of Valence, Arousal, and Dominance in each experimental condition. Besides the psychometric data, we also registered brainwave activity (EEG) and analyzed it with the 7 frequency bands. For EID, which was considerably higher in women, we found significant positive correlation with Valence (i.e., beneficial effect of the natural stimuli on the psycho-emotional status). At the same time, the analysis of the EEG data suggests a considerable impact of the VR immersion itself, with higher relaxation alpha effect in 3D vs. 2D condition in men. The novel and most pronounced effect of the gender factor was found in the relation between the EID and the EEG powers in the high-frequency bands—that is, positive correlation of these variables in women (0.64 < Rs < 0.74) but negative correlation in men (−0.66 < Rs < −0.72). Our results imply individually different and gender-dependent effects of the natural stimulus in VR. Correspondingly, the video and VR content development should consider this and aim to provide a user characteristics-tailored experience.
