摘要
研究了一个具有双奇异随机性的 Fitz Hugh-Nagumo( FHN)神经模型 .用参数β表示随机力在奇异点的奇异程度 ,当 β为非整数时 ,研究了奇异参数对 FHN模型相变的效应 .结果表明奇异参数β在 FHN系统的相变过程中起着十分重要作用 。
A FitzHugh Nagumo(FHN) neural model,which is double singular stochastic system, is studied.The effects of parameter β,which marks the singular degree of stochastic force at singular point, on the phase transition of the FHN model are discussed when β is non integer.It is shown that the parameter β plays an important role in phase transition of the system, and there is a locking phenomenon in the FHN model.
