Compared with the artificial neural network model, a biological neural network or a spiking neural network model has the distinctive feature that the difference between input spiking timings plays the key role in the determination of an output neuron's reactivity. The input vector space of a spiking neural network is also defined from the relative spiking timings. We here explore what response domain a spiking neural network can have depending on its structure. While the response domain of an output neuron, connected directly from input neurons, in an artificial neural network has a deterministic surface with the shape of a linear plane, that in the spiking neural network has a deterministic surface(s) with the shape of a closed or a curved plane. We suggest and demonstrate how a spiking neural network can have a variety of forms for response domains through not only a multilayer structure but also a complex structure having different connections numbers per signaling path. These results can be applied to understanding or designing a biological neural network with a perceptive function.
