Dependence of neural network synchronization on the extracellular electric field and neural morphology

Based on the two-compartment neuron model, the influence of neuronal morphology on firing and phase response curves (PRC) of cells are investigated. And by means of PRC, the relationship between neuronal morphology and network synchronization stimulated by extracellular electric field is studied. Results showed that the excitability of neurons can present different types when the morphological parameter is different. Furthermore, the sensitivity of neuronal synchronization to extracellular electric field has big difference for different morphological parameters.
