In this paper, the Ermentrout neuronal model under external electrical field is established. Based on this model we build a small-world neuronal network to study the spike-frequency adaptation of neuronal network under AC electrical field. The results show that when fixing the frequency, reducing the amplitude can improve the adaptability. And when fixing the amplitude, raising the frequency can improve...
Neuron encodes the information inputs from the dendrites by generating different firing patterns. The different firing patterns result from different action potential initial dynamic mechanisms. In this paper, we adopt a minimum neuron model, design the Wash-out filter from a physiological view, and achieve the transition between different action potential initial dynamic mechanisms. Finally, we demonstrate...
Neuron is the basic unit of neuron system and information processing. The response property and information coding style of neuron to external stimulus is realized essentially through change of neurons physiological characteristics. Some important properties of neuron, such as adaptability, sensitivity and reliability, are both closely related to neural coding. During sustained stimulation, neuron...
TMS (Transcranial magnetic stimulation) is an effective method of cortex stimulation for the treatment of neurological diseases. Here we change the magnetic stimulation into external electric field form and add it in a minimum neuron model. Through detailed analysis of phase plane and bifurcation type, we obtain the nonlinear kinetics law of the firing pattern change derive from external electric...
