Synchronization in a net of FitzHugh-Nagumo neurons — •A. Skupin¹ and L. Schimansky-Geier² — ¹Hahn-Meitner-Institut Glienicker Str. 100 14109 Berlin — ²Humboldt University Newtonstr. 15 12489 Berlin

While musing on Synchronization of clocks 100 years ago has led to Einsteins theory of relativity nowadays Synchronization plays an important role in different fields of science, specially in Statisical Physics, the other theory Einstein has instituted in his mirical year. In the last three decades Synchronization was detected as an important feature in neurophysiology, where different diseases like Parkinson disease can be explained by Synchronization of neurons. Thus motivated we study a net of FitzHugh-Nagumo neurons and its behaviour to an external stimulation and delay coupling. This will be compared with the Kuramoto model and a gaussian approximation.
