If the stimulus is removed, the corpuscle regains its shape and while doing so (i.e. Primates possess dermatoglyphics (the skin ridges responsible for fingerprints), but so do many other arboreal mammals. They are sensitive to shape and textural changes in exploratory and discriminatory touch. Their acute sensitivity provides the neural basis for reading Braille text. These corpuscles are especially susceptible to vibrations, which they can sense even centimeters away. [4][5][6][7][8] More specifically, they are primarily located in glabrous skin just beneath the epidermis within the dermal papillae.[9]. They are most concentrated in thick hairless skin, especially at the finger pads. The rate at which they are lost correlates well with the age-related loss in touch sensitivity for small probes (Thornbury and Mistretta, 1981). In particular, they have their highest sensitivity (lowest threshold) when sensing vibrations between 10 and 50 hertz. Sense hair movements.
