2 t, Y6 F) Y$ s& N) N; o6 x" R o On the cover: In this issue, Li et al. (pp. 1615–1627) use molecular genetics to label and visualize mechanosensory neurons that mediate touch perception at hair follicles in the skin. They find that each distinct class of hair follicle is innervated by a unique combination of mechanosensory neurons, making each type of hair follicle a functionally distinct mechanosensor. The cover image illustrates the complex pattern of mechanosensory neuron axon terminals encircling a guard hair follicle of a neuropeptide Y2 receptor-GFP (Npy2r-GFP) transgenic mouse. Nerve terminals expressing neurofilament 200 (NF200) are purple, whereas those expressing Npy2r-GFP are green. Double-positive fibers are white.
