Abstract
We study an encoding/decoding mechanism accounting for the relative spike tim-
ing of the signals propagating from peripheral nerve fibers to second-order so-
matosensory neurons in the cuneate nucleus (CN). The CN is modeled as a popu-
lation of spiking neurons receiving as inputs the spatiotemporal responses of real
mechanoreceptors obtained via microneurography recordings in humans. The ef-
