摘要
目的数值分析甲壳类动物胃肠神经系统神经元的电位发放。方法利用抑制神经系统的WLC(Winner less Competition)模型计算得到胃研磨和幽门神经系统的节律变化,数值说明龙虾胃研磨内的两侧牙齿和中间牙齿的运动出现切断食物、挤压食物和研磨食物的状态;结果幽门节律出现神经元AB(anterior burster)、PD(pyloric dilatator)和VD(ventricular dilator)之间的同步共振;胃研磨神经系统和幽门神经系统之间显示神经元LPG(lateral posterior gastricneuron)对神经元VD的发放传递等。结论数值结果再现了龙虾胃肠神经系统的实验现象。
Objective Using WLC model of inhibition neural system numerically analyzes neuron electric spike of crustacean stomatogastric ganglion to obtain the rhythm of gastric mill and pyloric network. Method The simulation method here show that the lateral teeth and the medial tooth of gastric network appear the states of cut, squeeze and grind of the food. Results The rhythm of pyloric network appears the synchronous oscillation of neurons AB, PD and VD. The gastric neural network and pyloric neural network appear the signal transmitting from neuron LPG to neuron VD. Conclusion These numerical results reveal the experiment phenomena of lobster stomatogastric neural system.
