Modeling of Brain-Like Concept Coding with Adulthood Neurogenesis in the Dentate Gyrus

Figure 3

The scatter plots of the relationship between similarities of the firing patterns of the EC and the firing patterns of GCs with neurogenesis a rate of 3 neurons/s and an input time interval of (a) 1 s, (b) 2 s, (c) 3 s, (d) 4 s, and (e) 5 s in the 200 GCs network with a maturation period of 5 s. Each dot represents one concept pair stimuli with similarity between the firing patterns of the EC shown along the horizontal axis and similarity between the firing patterns of GCs shown along the vertical axis. Sigmoidal relationship can be found between similarities of the firing patterns of the EC and those of GCs with input time interval of 5 s. Black dashed lines denote the limit above which pattern separation is performed in the model. TI: time interval.
