Abstract: Sustained activities are important to cognitive functions in neuroscience. The stability of one single firing signal propagating periodically in a neural loop coupled by chemical synaps-es(Tsodyks - Uziel - Markram model) is investigated in two ways. One is toinvestigate the initial statebasin of attraction under given system parameters;the other is to investigate the system parameter basin of attraction under one special initial condition. Based on the above results, two practicable approaches to promote periodic propagation stable, and one approach to inhabit propagations were propesed. The results of the two stimulations on one neuron approach may give hints to understand the reverberatory in biological experiments. These researches are important to understand the functions of loops in neural networks.

Key words: biological neural network, chemical synapse, loop, periodic propaga-tion, basin of attraction, Tsodyks-Uziel-Markram model
