Abstract:

The grid cell is a kind of important neuron cell related to spatial cognition and navigation in animal brain. It has hexagonal firing field extending to the whole two-dimensional space. The place cell is one of the main information sources of grid cells. The place cells can generate the grid cell through Hebbian learning, but the existing learning methods have assumed the Mexican hat model in advance for the adaptive function or learning window function of Hebbian learning. A place-to-grid cell model based on difference Hebbian learning is proposed. The input correlation with the Mexican hat model is generated spontaneously by using the difference of cells firing rates, and then the grid cell with the hexagonal firing field is generated through competitive nonlinear constraint of synaptic weights from place cells to the grid cell. The simulation results show that the difference Hebbian learning model can provide reference for the construction of the brain-inspired navigation system of unmanned platform.

Key words: brain-inspired navigation, grid cell, place cell, difference Hebbian learning, competitive nonlinear constraint
