We find, by numerical simulations, that neurons can exhibit different spiking patterns, which are well observed in the structure of the recurrence plot (RP). We further study the synchronization between weakly coupled neurons in chaotic regimes under the influence of a weak ELF electric field. In general, detecting the phases of chaotic spiky signals is not easy by using standard methods. Recurrence analysis provides a reliable tool for defining phases even for noncoherent regimes or spiky signals. Recurrence-based synchronization analysis reveals that, even in the range of weak coupling, phase synchronization of the coupled neurons occurs and, by adding an ELF electric field, this synchronization increases depending on the amplitude of the externally applied ELF electric field. We further suggest a novel measure for RP-based phase synchronization analysis, which better takes into account the probabilities of recurrences.<\/jats:p>","DOI":"10.3390\/e24020235","type":"journal-article","created":{"date-parts":[[2022,2,4]],"date-time":"2022-02-04T11:35:17Z","timestamp":1643974517000},"page":"235","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Recurrence-Based Synchronization Analysis of Weakly Coupled Bursting Neurons under External ELF Fields"],"prefix":"10.3390","volume":"24","author":[{"given":"Aissatou","family":"Nkomidio","sequence":"first","affiliation":[{"name":"Laboratory of Modelling and Simulation in Engineering, Biomimetics and Prototypes, Faculty of Sciences, University of Yaound\u00e9 I, Yaound\u00e9 812, Cameroon"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eulalie","family":"Ngamga","sequence":"additional","affiliation":[{"name":"Potsdam Institute for Climate Impact Research (PIK), Member of the Leibniz Association, Telegraphenberg, 14473 Potsdam, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7331-1115","authenticated-orcid":false,"given":"Blaise","family":"Nbendjo","sequence":"additional","affiliation":[{"name":"Laboratory of Modelling and Simulation in Engineering, Biomimetics and Prototypes, Faculty of Sciences, University of Yaound\u00e9 I, Yaound\u00e9 812, Cameroon"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5926-4276","authenticated-orcid":false,"given":"J\u00fcrgen","family":"Kurths","sequence":"additional","affiliation":[{"name":"Potsdam Institute for Climate Impact Research (PIK), Member of the Leibniz Association, Telegraphenberg, 14473 Potsdam, Germany"},{"name":"Department of Physics, Humboldt University of Berlin, 12489 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1437-7039","authenticated-orcid":false,"given":"Norbert","family":"Marwan","sequence":"additional","affiliation":[{"name":"Potsdam Institute for Climate Impact Research (PIK), Member of the Leibniz Association, Telegraphenberg, 14473 Potsdam, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Adrian, E.D.
