However, the neurophysiological mechanisms underlying these interventions remain poorly understood.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This pilot, exploratory, within-subject proof-of-concept study investigated the neurophysiological effects of mindfulness-based artistic\u2013contemplative sound pills in adults using EEG. Twelve participants were exposed to structured auditory interventions integrating poetic narratives, soundscapes, and mindfulness instructions. EEG activity was recorded before, during, and after the intervention, and spectral power across frequency bands was analyzed using linear mixed-effects models. Subgroup analyses by artistic modality (visual arts, dance, music, and theater) were also performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>At the group level, exploratory analyses indicated a statistically significant modulation of high-frequency beta activity (20\u201330 Hz), characterized by a reduction during the intervention compared to the pre-intervention baseline, followed by a return toward baseline levels in the post-intervention phase. No statistically significant global changes were observed in the other frequency bands examined, including alpha (8\u201312 Hz), theta (4\u20138 Hz), delta (0.5\u20134 Hz), mu, low-frequency beta (12\u201320 Hz), and the combined theta + alpha band. Subgroup analyses by artistic modality suggested descriptive, modality-specific oscillatory patterns; however, these findings should be interpreted as hypothesis-generating only, given the very small sample sizes per modality (n = 2\u20134) and the absence of a control condition.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Overall, the results provide preliminary evidence that artistic\u2013contemplative auditory interventions can modulate neural oscillatory dynamics, particularly within the high-frequency beta range. Given the small sample size, within-subject design, and lack of a control condition, these findings should be interpreted with caution and require confirmation in larger controlled studies.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpsyg.2026.1846392","type":"journal-article","created":{"date-parts":[[2026,7,28]],"date-time":"2026-07-28T15:36:57Z","timestamp":1785253017000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["EEG signatures of mindfulness-based artistic\u2013contemplative sound interventions: a pilot study on aesthetic states of consciousness"],"prefix":"10.3389","volume":"17","author":[{"given":"Hercules","family":"Morais","sequence":"first","affiliation":[{"name":"Department of Preventive Medicine, Escola Paulista de Medicina, Federal University of S\u00e3o Paulo (UNIFESP)","place":["S\u00e3o Paulo, Brazil"]},{"name":"Area of Basic Psychology, Faculty of Social and Labour Sciences, University of Zaragoza","place":["Zaragoza, Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D\u00e9bora Regina","family":"de Aguiar","sequence":"additional","affiliation":[{"name":"Program in Evidence-Based Health, Department of Medicine, Federal University of S\u00e3o Paulo (UNIFESP)","place":["S\u00e3o Paulo, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matheus Hissa Louren\u00e7o","family":"Ferreira","sequence":"additional","affiliation":[{"name":"EEFFTO, Sport Sciences, Federal University of Minas Gerais (UFMG)","place":["Belo Horizonte, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patr\u00edcia Zocchi","family":"dos Santos","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Hospital das Cl\u00ednicas, University of S\u00e3o Paulo (HCFMUSP)","place":["S\u00e3o Paulo, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juliana","family":"Zellauy","sequence":"additional","affiliation":[{"name":"Escola de Ci\u00eancias da Sa\u00fade e da Vida, Departamento de Neuroci\u00eancias e Comportamento, Pontifical Catholic University of Rio Grande do Sul (PUCRS)","place":["Porto Alegre, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana Cristina Fraga da Silva","family":"Schwingel","sequence":"additional","affiliation":[{"name":"Training and Development Center of the Chamber of Deputies (CEFOR)","place":["Bras\u00edlia, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulina","family":"Lamas-Morales","sequence":"additional","affiliation":[{"name":"Area of Basic Psychology, Faculty of Social and Labour Sciences, University of Zaragoza","place":["Zaragoza, Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Javier","family":"Garc\u00eda Campayo","sequence":"additional","affiliation":[{"name":"Department of Medicine, Psychiatry and Dermatology, Faculty of Medicine, University of Zaragoza","place":["Zaragoza, Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yolanda","family":"L\u00f3pez del Hoyo","sequence":"additional","affiliation":[{"name":"Area of Basic Psychology, Faculty of Social and Labour Sciences, University of Zaragoza","place":["Zaragoza, Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcelo","family":"Demarzo","sequence":"additional","affiliation":[{"name":"Mente Aberta - The Brazilian Center for Mindfulness and Health Promotion, Escola Paulista de Medicina, Federal University of S\u00e3o Paulo (UNIFESP)","place":["S\u00e3o Paulo, Brazil"]},{"name":"Cons\u00f3rcio Acad\u00eamico Brasileiro de Sa\u00fade Integrativa (CABSIN)","place":["S\u00e3o Paulo, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,7,28]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"2955","DOI":"10.1017\/S0033291716001665","article-title":"Mental disorders among college students in the World Health Organization world mental health surveys","volume":"46","author":"Auerbach","year":"2016","journal-title":"Psychol.
