The sympathetic deficit on the denervated side causes the flushing of the opposite side to appear more pronounced.

To assess contractility of denervated leg muscles, rheobase and chronaxie were determined in anaesthetized rat by surface electrical stimulation and palpation of the leg muscles.

An intact sympathetic nervous system is required to maintain full cellular immunoregulation as denervated mice do not produce and activate, for example, splenic suppressor T cells, or thymic NKT cells.
