Temperature Discrimination in the Skin

THERMORECEPTORS reported in the skin of the cat, rat and dog1–3 had properties similar to the thermoreceptors found in the tongue4. The afferent fibres, however, had low conduction velocities characteristic of non-myelinated axons. The receptors fell into two categories: those excited by a rise and those excited by a fall in cutaneous temperature, above or… CONTINUE READING
