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. In order to solve the problem of information transfer from grid cells to location cells in mouse hippocampal formation, a competitive neural network model of grid cells to location cells was constructed.The simulation results in one-dimensional and two-dimensional environments were in accordance with the biological research results, The model can simulate the discharge characteristics of the cells in the dentate gyrus and the hippocampus, which can effectively explain the formation mechanism of the position cell location field.
