Spike timing flows.

<p>Presented here are different possible dynamics of spike timing in a two dimensional network. The top, middle and bottom rows correspond to fixed point dynamics, or synchrony, limit cycle or asynchrony, and monostability, where there is a weakly stable fixed point, which can be perturbed to produced transient trajectories (red dashes). <b>A</b>: phase response curves of the two neurons in the network, normalized by the magnitude of coupling strength. <b>B</b>: time series of the spiking dynamics <b>C</b>: The mean field is shown in gray and the relative spike timing modulo the period is shown by the dashed line. Both indicators of phase organization show the distinct qualitative differences in dynamics between the three phase flows.
