20.500.12556/DKUM-66388 Autapse-induced multiple coherence resonance in single neurons and neuronal networks We study the effects of electrical and chemical autapse on the temporal coherence or firing regularity of single stochastic Hodgkin-Huxley neurons and scale-free neuronal networks. Also, we study the effects of chemical autapse on the occurrence of spatial synchronization in scale-free neuronal networks. Irrespective of the type of autapse, we observe autaptic time delay induced multiple coherence resonance for appropriately tuned autaptic conductance levels in single neurons. More precisely, we show that in the presence of an electrical autapse, there is an optimal intensity of channel noise inducing the multiple coherence resonance, whereas in the presence of chemical autapse the occurrence of multiple coherence resonance is less sensitive to the channel noise intensity. At the network level, we find autaptic time delay induced multiple coherence resonance and synchronization transitions, occurring at approximately the same delay lengths. We show that these two phenomena can arise only at a specific range of the coupling strength, and that they can be observed independently of the average degree of the network. neuronal dynamics autapse coherence resonance scale-free network nevronska dinamika avtapsa koherenčna resonanca brez-skalna mreža true true true Angleški jezik Slovenski jezik Članek v reviji 2017-06-23 09:42:29 2017-06-23 09:45:49 2024-09-02 13:30:13 2019-07-11 15:45:48 2016 0 0 str. 1-14 Letn. 6 2016 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2016-05-28 2016-07-08 2016-08-02 2045-2322 53 18727432 22456072 10.1038/srep30914 2045-2322 URN:SI:UM:DK:IWNKL6VW Scientific_Reports_2016_Yilmaz_et_al._Autapse-induced_multiple_coherence_resonance_in_single_neurons_and_neuronal_networks.pdf Scientific_Reports_2016_Yilmaz_et_al._Autapse-induced_multiple_coherence_resonance_in_single_neurons_and_neuronal_networks.pdf 1 5DEFAA9E01B20B9C8B51B4BD2EE03032 f5339d2f6b7c7a8548f399c5888c6975f2b758c76983122de39d7abb10e16761 494e5036-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=112989 http://www.nature.com/articles/srep30914 1 https://dk.um.si/Dokument.php?lang=slv&id=112988 Fakulteta za naravoslovje in matematiko 0 0 0
