Regulation of Skin Temperatures after Lesions of Spinal Nerve Roots

Abstract

Summary

1. Deafferentation of a cat's forelimb does not lower the skin temperature of the footpad which may remain similar to the contralateral normally innervated one or may be warmer. 2. Deafferentation of a hindlimb may not affect the pad temperature, or it may be lowered or raised. 3. Any differences present in the fore-limbs or in the hindlimbs disappear after bilateral sympathectomy. 4. Section of the L₆-L₇ and S₁-S₂ ventral roots of a cat may not significantly affect the pad temperatures.
