Impact of Adaptation Currents on Synchronization of Coupled Exponential Integrate-and-Fire Neurons

Figure 7

Effects of conduction delays on the stability of synchrony in coupled pairs.

Spike times (solid bars) of two neurons oscillating with a small phase difference and coupled through excitatory (A and B) or inhibitory synapses (C and D) with a symmetric conduction delay . The PRCs of the neurons that make up each pair are displayed below. In A and C the neurons have type I PRCs, in B and D the PRCs are type II. The time (phase) at which each neuron receives a synaptic current is shown along the spike trace. Phase advances or delays, considering the time of input arrival and the shape of the PRC, are indicated by advanced or delayed subsequent spike times. Dashed bars indicate spike times without synaptic inputs. The consequent changes in are highlighted.
