In this study, we propose that in a pool of neurons recurrently coupled through delayed synaptic connections transient patterns of synchrony can be observed due to the changing incoming stimuli, in continuance of some recent works . Transient synchrony between spiking activity of the neurons has been reported in different sensory tasks e.g. visual and olfactory system [2, 3].
We have shown that the ability of a neural network to switch between coherent and incoherent firing, may be dependent on the delay in communication between neurons. It has been shown that two reciprocally coupled neurons can fire inphase if the delays lie in the region where the phase response curve of the neurons have negative slope, otherwise their firing is antiphase. In the larger networks where the neurons connect to several other neurons, inphase firing state remains stable where instead of antiphase state, several stable states appear. This is related to geometric frustration in condensed matter physics where a plenitude of distinct ground states are ensued by the lattice structure as in Ising system.
