针对老鼠海马结构中网格细胞到位置细胞的信息传递问题,构建网格细胞到位置细胞的竞争型神经网络模型.在一维和二维环境中的仿真结果均符合生物学研究事实,结果表明,模型能够模拟齿状回和海马中位置细胞的放电特性,可有效解释位置细胞位置野的形成机理.
For the problem of the information transmission between grid cells and place cells in rat's hippocampal formation,a competitive neural network model from grid cells to place cells is proposed. The simulation results in both one and two dimension environment are consistent with the existent biology facts, which show that the model can simulate the firing characteristics of place cells of Dentate Gyms and Hippocampus, and can be used to explain the formation mechanism of the place field effectively.
