The vast majority of large-diameter neurons are myelinated, and few express the proprioceptive marker parvalbumin. A, Examples of retrogradely labeled large-diameter neurons and their expression of CGRP, N52, or parvalbumin. Top row, Large-diameter CGRP-negative, muscle-projecting, N52-positive neuron. Middle row, Large-diameter CGRP-positive, skin-projecting, N52-positive neuron. Lower row, Large-diameter CGRP-negative, muscle-projecting, parvalbumin-positive neuron. B, A total of 82%–100% of large-diameter neurons are N52-positive. C, Few neurons projecting to muscle are parvalbumin-positive.
