Spatiotemporal Processing in a Spiking Neural P System

There has been considerable recent activity in the area of Spiking Neural P systems and notably, their extension by the simulation of astrocytes. Work in this area has focused on intracellular interaction between astrocytes and neurons. This paper further extends this idea by considering extracellular communication between astrocytes, in particular linking the astrocytes in a network that draws on the powerful feature extraction properties of a ¿reservoir computer¿. Also, current spiking neural P systems model the synapse in a simplistic way that does not take account of the effects of varying axon length. In an attempt to address this, the authors discuss the use of fuzzy techniques as a possible means to model the effect of axonal length on the post synaptic potential in a more realistic way.
