| Abstract: | The paper studies action potential and network properties of retina neural system and lamprey neural system. The inhibited neural systems, WinnerLess Competition（WLC）model, are used here to study the potential spike of retina and lamprey neural system and we obtain the pattern of their electric spike. With help of properties of Watts-Strogatz small world network,the indexes of clustering coefficient and characteristic length of these two biology systems tell us the massage transmitting of these two neural systems have properties of small world network. |
