Spike-timing in primary sensory neurons: a model of somatosensory transduction in the rat

Abstract In previous work, we constructed a simple electromechanical model of transduction in the rat mystacial follicle that was able to replicate primary afferent response profiles to a variety of whisker deflection stimuli. Here, we update that model to fit newly available spike-timing response data, and demonstrate that the new model produces appropriate responses to richer stimuli, including pseudo white noise and natural textures, at a spike-timing level of detail. Additionally, we demonstrate reliable distributed encoding of multicomponent oscillatory signals. No modifications were necessary to the mechanical model of the physical components of the follicle
