Standard neural network theory describes the neuron as an input-output unit with a nonlinear transfer function. Real biological neurons are much more complicated than that. They have an intrinsic dynamics which transforms the input into a sequence of electrical pulses, the so-called action potentials or spikes which are transmitted along the axon to other neurons. The exact timing of spikes can, in principle, convey a lot of information which is lost if only the temporally averaged mean firing rate is considered. During recent years, an increasing amount of experimental evidence has accumulated which shows that temporal information plays indeed a role in several biological neural systems.
In this line of research we study neural network models with spiking neurons. We address, among others, the following questions:
- What is a useful level of description of spiking activity?
- Do we need a large set of differential equations for every neuron or is a description by a threshold model good enough?
- What are the global states in large networks of spiking neurons? * How is information transmitted between population of neurons?
