Abstract: Mechanical and thermal stimuli acting on the skin are detected by morphologically and physiologically distinct sensory neurons of the dorsal root ganglia (DRG). Achieving a holistic view of how this diverse neuronal population relays sensory information from the skin to the central nervous system (CNS) has been challenging with existing tools. Here, we used transcriptomic datasets of the mouse DRG to guide development and curation of a genetic toolkit to interrogate transcriptionally defined DRG neuron subtypes. Morphological analysis revealed unique cutaneous axon arborization areas and branching patterns of each subtype. Physiological analysis showed that subtypes exhibit distinct thresholds and ranges of responses to mechanical and/or thermal stimuli. The somatosensory neuron toolbox thus enables comprehensive phenotyping of most principal sensory neuron subtypes. Moreover, our findings support a population coding scheme in which the activation thresholds of morphologically and physiologically distinct cutaneous DRG neuron subtypes tile multiple dimensions of stimulus space.

Animal development is directed by a genetic toolkit shared by all animals — from fruit flies to frogs to human beings — rather than different animals having different genetic toolkits. UCLA Professor of Biological Chemistry Edward De Robertis explains that the field of evolutionary development (or Evo-Devo) seeks to understand how so many beautiful animal forms evolved through the use of the original genetic toolkit of the last common ancestor of all animals, urbilateria, which existed at least 560 million years ago.
