%0 Generic %D 2009 %T New normal forms for spiking neural P systems %A Linqiang Pan %A Gheorghe Paun %C Sevilla, España %I Fénix Editora %P 127-138 %U http://www.gcn.us.es/?q=node/414 %V II %X 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. %8 02/02/2009 %@ 978-84-613-2839-0
