Abstract

âº We show an ultra-late potential relating to unmyelinated touch afferent input. âº This C-tactile fiber potential is of very different time course than from A-fibers. âº The slow-onset potential is located over frontal, central electrodes. âº The paradigm tests small fiber function without using painful stimuli.
