Abstract. We study how primary tactile afferents encode relevant con-
tact features to mediate early processing of haptic information. In this
paper, we apply metrical information theory to perform temporal de-
coding of human microneurography data. First, we enrich the theory by
deriving a novel spike train metrics inspired by neuronal computation.
This spike train metrics can be interpreted biologically and its behaviour
is not influenced by spontaneous activity, which decreases the ability of
other spike metrics to separate input patterns. Second, we employ our
metrical information tools to demonstrate that primary spiking signals
