In this regard, a relevant question concerns the processing of signals deriving from the internal body and their contribution to interpersonal synchronization. This study aims to assess hemodynamic inter-subject coherence in the prefrontal cortex (PFC) through functional near-infrared spectroscopy (fNIRS) hyperscan recording during dyadic synchronization tasks proposed with or without a social frame and performed in two distinct interoceptive conditions: focus and no focus on the breathing condition. Individuals\u2019 hemodynamic data (oxygenated and de-oxygenated hemoglobin (O2Hb and HHb, respectively)) were recorded through fNIRS hyperscanning, and coherence analysis was performed. The findings showed a significantly higher O2Hb coherence in the left PFC when the dyads performed the synchronization tasks with a social frame compared with no social frame in the focus condition. Overall, the evidence suggests that the interoceptive focus and the presence of a social frame favor the manifestation of a left PFC interpersonal tuning during synchronization tasks.<\/jats:p>","DOI":"10.3390\/info14020058","type":"journal-article","created":{"date-parts":[[2023,1,18]],"date-time":"2023-01-18T03:04:44Z","timestamp":1674011084000},"page":"58","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Inter-Brain Hemodynamic Coherence Applied to Interoceptive Attentiveness in Hyperscanning: Why Social Framing Matters"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8634-1951","authenticated-orcid":false,"given":"Michela","family":"Balconi","sequence":"first","affiliation":[{"name":"International Research Center for Cognitive Applied Neuroscience (IrcCAN), Universit\u00e0 Cattolica del Sacro Cuore, 20123 Milan, Italy"},{"name":"Research Unit in Affective and Social Neuroscience, Department of Psychology, Universit\u00e0 Cattolica del Sacro Cuore, 20123 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3027-2272","authenticated-orcid":false,"given":"Laura","family":"Angioletti","sequence":"additional","affiliation":[{"name":"International Research Center for Cognitive Applied Neuroscience (IrcCAN), Universit\u00e0 Cattolica del Sacro Cuore, 20123 Milan, Italy"},{"name":"Research Unit in Affective and Social Neuroscience, Department of Psychology, Universit\u00e0 Cattolica del Sacro Cuore, 20123 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,17]]},"reference":[{"key":"ref_1","first-page":"501","article-title":"Interoception and Mental Health: A Roadmap","volume":"3","author":"Khalsa","year":"2018","journal-title":"Biol.
