Abstract: Hodgkin-Huxley model has been used for the research on behaviors and characteristics of a single neuron, which failed to make up of neural network system. The HH model was proposed according to the inhibitory connection and excitatory connection among neurocytes, and a neural population system was outlined based on HH model to simulate the biological configuration and lateral inhibition of!the cortical columns. Lateral inhibition of cortical columns was applied to coding and decoding of the neural population to realize position tracking. Then the decoding strategy was changed to carry out the function of winnertakeall. The experiments verify the accuracy of position tracking and the improvement of winner-take-all on account of lateral inhibition in cortical columns.

Key words: HH model, neural population, lateral inhibition of cortical column, position tracking, winner-take-all
