Sttbthreshold dynamics and its effect on signal transduction in a netrral systetta are studied bytrsing the Hindmarsh-Rose neuron naodel. Under a periodic stinatrlation, as the constant biasof the stinutrlvts increases, the neturon exhibits subthreshold periodic and sulothreshold chaoticresponses, suprathreshold chaotic firing of spikes, and unode-locked firing. The phase diagrau-nof' the system is obtained. The dynamic behavior obtained is in agreeraaent with experiraaents onthe sqtrid giant axon. In partictrlatr, the subthreshold periodic oscillatory state is related to anttmber of experinaental restrlts, sttch as those fotrnd in the netmrons of the inferior olivary ntmcleus.lVIore itnportantly, we also find that subthreshold clraotic responses play a role analogotrs to theinternal deterministic noise, and can enhance weak signal transduction via a unechanistn similarto stochastic resonance.
