A map of bursting activities derived from multiple simulations of the excitatory neuron population and presented in a 2D parameter space (gtonic, ), where gtonic is the external excitatory drive to all neurons, N is the number of neurons in the population, and is the average weight of mutual excitatory synaptic interactions within the population. Bursting activities involving different mechanisms are distinguished by color. The area for INaP-dependent population bursting is shown blue; the area in which population bursting may be based on either INaP or ICAN is shown green; the area in which population bursting may exist without both of these currents is shown gray; an additional area (brown) represents an unstable ICAN-dependent bursting.
