In this context, the widespread use of bivariate statistical association measures often results in a false identification of links because strong similarity between two time series can also emerge without the presence of a direct interaction due to intermediate mediators or common drivers. In order to properly distinguish such direct and indirect links for the special case of event-like data, we present here a new generalization of event coincidence analysis to a partial version thereof, which is aimed at excluding possible transitive effects of indirect couplings. Using coupled chaotic systems and stochastic processes on two generic coupling topologies (star and chain configuration), we demonstrate that the proposed methodology allows for the correct identification of indirect interactions. Subsequently, we apply our partial event coincidence analysis to multi-channel EEG recordings to investigate possible differences in coordinated alpha band activity among macroscopic brain regions in resting states with eyes open (EO) and closed (EC) conditions. Specifically, we find that direct connections typically correspond to close spatial neighbors while indirect ones often reflect longer-distance connections mediated via other brain regions. In the EC state, connections in the frontal parts of the brain are enhanced as compared to the EO state, while the opposite applies to the posterior regions. In general, our approach leads to a significant reduction in the number of indirect connections and thereby contributes to a better understanding of the alpha band desynchronization phenomenon in the EO state.<\/jats:p>","DOI":"10.1063\/5.0087607","type":"journal-article","created":{"date-parts":[[2022,6,24]],"date-time":"2022-06-24T12:47:52Z","timestamp":1656074872000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":2,"title":["Partial event coincidence analysis for distinguishing direct and indirect coupling in functional network construction"],"prefix":"10.1063","volume":"32","author":[{"given":"Jiamin","family":"Lu","sequence":"first","affiliation":[{"name":"School of Physics and Electronic Science, East China Normal University 1 , Shanghai 200062, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7023-6375","authenticated-orcid":false,"given":"Reik V.","family":"Donner","sequence":"additional","affiliation":[{"name":"Department of Water, Environment, Construction and Safety, Magdeburg\u2013Stendal University of Applied Sciences 2 , Breitscheidstra\u00dfe 2, 39114 Magdeburg, Germany"},{"name":"Potsdam Institute for Climate Impact Research (PIK) \u2013 Member of the Leibniz Association 3 , Telegrafenberg A31, 14473 Potsdam, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dazhi","family":"Yin","sequence":"additional","affiliation":[{"name":"Key Laboratory of Brain Functional Genomics (Ministry of Education and Shanghai), School of Psychology and Cognitive Science, East China Normal University 4 , Shanghai 200062, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8512-371X","authenticated-orcid":false,"given":"Shuguang","family":"Guan","sequence":"additional","affiliation":[{"name":"School of Physics and Electronic Science, East China Normal University 1 , Shanghai 200062, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3241-3139","authenticated-orcid":false,"given":"Yong","family":"Zou","sequence":"additional","affiliation":[{"name":"School of Physics and Electronic Science, East China Normal University 1 , Shanghai 200062, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2022,6,24]]},"reference":[{"key":"2023080922073539600_c1","doi-asserted-by":"publisher","first-page":"175","DOI":"10.1016\/j.physrep.2005.10.009","article-title":"Complex networks: Structure and dynamics","volume":"424","year":"2006","journal-title":"Phys.
