Abstract

Untangling the neural code underlying sensory perception
requires the mapping of physical stimulus parameters to neuronal responses. The speed by which rodents discriminate between
tactile stimuli, and neuronal response reliability in the whisker
somatosensory system suggest that temporal coding might be
used to encode sensory stimuli. The interaction between
whiskers and object surfaces induces a complex temporal pattern of whisker vibration which may carry important tactile
information. To determine the temporal kinetic features of whisker motion that are represented by first-order sensory neurons,
we recorded from trigeminal ganglion neurons (TG) during
stimulation with complex pattern of whisker vibration. We find
that each of the different TG mechanoreceptor subtypes transmits a distinct kinetic feature of the stimulus. Our results suggest
that TG neurons transmit a distributed representation of whisker
motion, based on tactile kinetic features.
