Controlling the Speed of Synfire Chains

This paper deals with the propagation velocity of synnre chain activation in locally connected networks of artiicial spiking neu-rons. Analytical expressions for the propagation speed are derived taking into account form and range of local connectivity, explicitly modelled synaptic potentials, transmission delays and axonal conduction velocities. Wave velocities particularly depend on the level of external input to the network indicating that synnre chain propagation in real networks should also be controllable by appropriate inputs. The results are numerically tested for a network consisting ofìntegrate-and-re' neurons.
