	abstract = {With a motivation related to gene expression, where enzymes act in series,
somewhat similar to the train spikes traveling along the axons of neurons, we consider
an extension of spiking neural P systems, where several types of \spikes" are allowed.
The power of the obtained spiking neural P systems is investigated and the modeling of
gene expression in these terms is discussed. Some further extensions are mentioned, such
as considering a process of decay in time of the spikes.},
