Figure 16

Quality of spiking grid cell learning, in response to stripe cells with a spacing of 20 cm, as a function of number of bits available to store synaptic weights with regard to (a) grid score, (b) inter-trial stability, and (c) percentage of learned grid cells at the end of 10 trials. Panel (d) shows the absolute relative change in weights from input stripe cells, as a percentage, through the tenth trial as a function of number of bits.
