In this dissertation, two  spatially extended networks of FitzHugh-Nagumo  neurons operating in the subexcitable and  hyperexcitable regime are studied by computational  methods, leading to two key conclusions.  First, the length and speed of perturbation  propagation in the subexcitable FitzHugh-Nagumo  system is maximized by spatiotemporal noise of  optimal intensity. This indicates that random  fluctuations in neuronal excitability can enhance  perturbation propagation in the nervous system.  Second, defining novel measures to characterize the synchronization of hyperexcitable FitzHugh-Nagumo  oscillator networks for various strengths of phase- attractive and phase-repulsive coupling, significant  differences in calcium dynamics can be shown between  astrocyte cultures originating from epileptic and  normal brain tissue.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838342276\"\u003e\u003ch3\u003eNoise-enhanced inter-celullular communication in neuronal networks and oscillation synchrony in  epileptic tissue\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838342276","offer_id":39498931830877,"sku":"9783838342276","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/e4003108-c666-4c95-8f83-535aec1b8437.jpg?v=1773385848","url":"https:\/\/shop.autorenwelt.de\/products\/beneficial-noise-and-perilous-oscillations-in-the-nervous-system-von-gabor-balazsi-und-frank-moss","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
