The fractional-order modeling and synchronization of electrically coupled neuron systems

2012Hashim I.JournalMoaddy K.Momani S.Radwan A.G.Salama K.N.

In this paper, we generalize the integer-order cable model of the neuron system into the fractional-order domain, where the long memory dependence of the fractional derivative can be a better fit for the neuron response
