20.500.12556/DKUM-66300 Synchronous bursts on scale-free neuronal networks with attractive and repulsive coupling This paper investigates the dependence of synchronization transitions of bursting oscillations on the information transmission delay over scale-free neuronal networks with attractive and repulsive coupling. It is shown that for both types of coupling, the delay always plays a subtle role in either promoting or impairing synchronization. In particular, depending on the inherent oscillation period of individual neurons, regions of irregular and regular propagating excitatory fronts appear intermittently as the delay increases. These delay-induced synchronization transitions are manifested as well-expressed minima in the measure for spatiotemporal synchrony. For attractive coupling, the minima appear at every integer multiple of the average oscillation period, while for the repulsive coupling, they appear at every odd multiple of the half of the average oscillation period. The obtained results are robust to the variations of the dynamics of individual neurons, the system size, and the neuronal firing type. Hence, they can be used to characterize attractively or repulsively coupled scale-free neuronal networks with delays. synchronization neuronal networks noise stochastic processes scale-free networks information transmission delay sinhronizacija nevronske mreže šum stohastični procesi scale-free mreže zamik prenosa informacij true true true Angleški jezik Slovenski jezik Članek v reviji 2017-06-19 13:18:36 2017-06-19 13:19:19 2024-05-28 11:43:57 2019-07-11 15:42:48 2011 0 0 str. 1-10 št. 1 Letn. 6 2011 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1932-6203 530.16 2005896 14725142 10.1371/journal.pone.0015851 1932-6203 URN:SI:UM:DK:QSFVLUVZ PLoS_ONE_2011_Wang,_Chen,_Perc_Synchronous_Bursts_on_Scale-Free_Neuronal_Networks_with_Attractive_and_Repulsive_Coupling.PDF PLoS_ONE_2011_Wang,_Chen,_Perc_Synchronous_Bursts_on_Scale-Free_Neuronal_Networks_with_Attractive_and_Repulsive_Coupling.PDF 1 1DE719156A4B164810F0142664605BF3 6177b2792353f4d83f85612eabbc7af2c8d3f48983deaa38ce33c721997279d5 43db9711-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=112784 http://dx.plos.org/10.1371/journal.pone.0015851 1 https://dk.um.si/Dokument.php?lang=slv&id=112783 Fakulteta za naravoslovje in matematiko 0 0 0
