ing reduced systems, and we plot the coincidence factors for a range of reduced system
sizes in Figure 3.8. In general, the reduced systems are successful at capturing the
spiking dynamics of each cell, and they simulate faster than their full system coun-
terparts. Additionally, the voltage dynamics at any location can be recovered from
the reduced system, not just the somatic potential (for example, see Figure 3.7).
