How does the parasympathetic nervous system affect the liver?

Stimulation of several brain areas has been shown to induce similar changes in liver glucose metabolism as produced by direct stimulation of sympathetic or parasympathetic nerves. These brain areas are either proposed or proven to be able to affect liver glucose metabolism via their effect on autonomic neuronal output.
