PHASE SYNCHRONIZATION IN COUPLED NEURONS UNDER EXTERNAL LOW
Hongling Zhuang*
ABSTRACT
Synchronization of neurons helps maintain certain physiological functions in the brain, and networks of synchronized neurons have been studied extensively, In this paper, based on the ML neuron model, the synchronous firing behavior of coupled neurons under external low-frequency signals is discussed. The synchronous transition between bursting and spikes within the bursting can occur simultaneously. The neurons showed complete synchronization, anti-phase synchronization of spikes within the bursting and bursting, anti-phase synchronization of within the bursting and in-phase synchronization of bursting, and the number of spikes within the bursting increases with the increase of coupling strength. The effect of coupling intensity on neuronal firing was analyzed by the phase difference of spikes, the phase difference of bursting and inter-peak interval (ISI). The pathological changes and disorders of the brain are closely related to the synchronous behavior of neurons, and abnormal synchronization will lead to the occurrence of a variety of nervous system diseases. The research results help us to understand the occurrence of different functions in the human brain and the generation of diseases, and provide a certain basis for brain science.
