The change curve of the number of cells in the position where the maturity reaches 95%. As the number of training times increases, the number of place cells where the maturity reaches 95% gradually increases. In the 4th training, the number of place cells in the 95% maturity increased rapidly from 11 to 43. Moreover, at the end of the 7th training, there were 49 place cells reaching 95% maturity.
