Information in a Network of Neuronal Cells: Effect of Cell Density and Short-Term Depression

Figure 2

Nodes are divided into firing, delivering a signal, and target, receiving a signal: a target neuron can receive current pulses from multiple sources; in turn a firing neuron can deliver current pulses to multiple targets (a); the sum of multiple stimuli in a neuron modifies the potential across its membrane until it surpasses a limiting or threshold value: in this circumstance, the neuron generates an action potential (b).
