More recent evidence depicts the cortex as a dynamic system, organized into flexible networks with patterns of spatiotemporal activity corresponding to attentional demands. In functional MRI (fMRI), dynamic analysis of such spatiotemporal patterns is highly promising for providing non\u2010invasive biomarkers of neurodegenerative diseases and neural disorders. However, there is no established neurotypical spectrum to interpret the burgeoning literature of dynamic functional connectivity from fMRI across attentional states. In the present study, we apply dynamic analysis of network\u2010scale spatiotemporal patterns in a range of fMRI datasets across numerous tasks including a left\u2013right moving dot task, visual working memory tasks, congruence tasks, multiple resting state datasets, mindfulness meditators, and subjects watching TV. We find that cortical networks show shifts in dynamic functional connectivity across a spectrum that tracks the level of external to internal attention demanded by these tasks. Dynamics of networks often grouped into a single task positive network show divergent responses along this axis of attention, consistent with evidence that definitions of a single task positive network are misleading. Additionally, somatosensory and visual networks exhibit strong phase shifting along this spectrum of attention. Results were robust on a group and individual level, further establishing network dynamics as a potential individual biomarker. To our knowledge, this represents the first study of its kind to generate a spectrum of dynamic network relationships across such an axis of attention.<\/jats:p>","DOI":"10.1002\/hbm.70049","type":"journal-article","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T04:22:26Z","timestamp":1740111746000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Infraslow Dynamic Patterns in Human Cortical Networks Track a Spectrum of External to Internal Attention"],"prefix":"10.1002","volume":"46","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8765-2233","authenticated-orcid":false,"given":"Harrison","family":"Watters","sequence":"first","affiliation":[{"name":"Emory Neuroscience Graduate Program Emory University  Atlanta Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleah","family":"Davis","sequence":"additional","affiliation":[{"name":"Agnes Scott College  Decatur Georgia USA"},{"name":"School of Psychology Georgia Institute of Technology  Atlanta Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abia","family":"Fazili","sequence":"additional","affiliation":[{"name":"Emory Neuroscience Graduate Program Emory University  Atlanta Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lauren","family":"Daley","sequence":"additional","affiliation":[{"name":"School of Psychology Georgia Institute of Technology  Atlanta Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.
