Pacinian corpuscles are mechanoreceptors tuned to detect high-frequency, low-amplitude signals. Found in human palm and fingertips, they are useful for discrimination of rough and smooth textures, a sensitivity seemingly amplified by the ridges of fingerprints. Wende et al. identified a mutation in humans that disrupts this sensitivity to texture but leaves other facets of touch, such as tactile spatial acuity, intact.
