Abstract
Numerical calculations have been made on the consistent spike-train response of a pair of locus ceruleus (LC) neurons coupled by synapse. The coupled, excitable LC neurons are assumed to receive the constant, periodic and chaotic external stimulus at dendrite of the neuron, and whose soma potential being adopted to driving the other one along axon. With appropriated stimulus and coupling strength, the synchronization oscillation between the two neurons is well preserved even when the external stimulus is chaotic, for the small time scale stimulus, one inspiring simulations results, the wave shape or chaotic attractor of stimulus could be transmitted completely by neuronal ISIs sequence, including the periodic, chaotic characters of stimulus, such as, phase space or chaotic attractors, but this phenomenon disappears for big time scale stimulus.
