	abstract = {We consider a natural restriction in the architecture of a spiking neural P
system, namely, to have neurons of a small number of types (i.e., using a small number of
sets of rules), and we prove that three types of neurons are sufficient in order to generate
each recursively enumerable set of numbers as the distance between the first two spikes
emitted by the system or as the number of spikes in a specified neuron, in the halting
configuration. The case we investigate is that of spiking neural P systems with standard
rules, with delays, but without using forgetting rules; similar normal forms remain to be
found for other types of systems.
