Sympathetic cholinergic outflow using dynamic evaluation of postganglionic sudomotor activity (DEPSA)

      Introduction: Sweating stimulation by iontophoresis of cholinergic agonists produces a sudomotor response not only in the stimulated area but also in adjacent regions. This property is due to the activation of the postganglionic axo-axonic reflex. It is particularly useful to detect peripheral autonomic neuropathies associated with the functional decrease of the activity of sympato-cholinergic postganglionic neurons.
