Spinally projecting preproglucagon axons preferentially innervate sympathetic preganglionic neurons.
Bottom Line: These results show that brainstem PPG neurons innervate spinal autonomic and somatic motor neurons.SPN receive the densest PPG innervation.Brainstem PPG neurons could directly modulate sympathetic outflow through their spinal inputs to SPN or interneurons.

Mentions: Many non-varicose YFP-immunoreactive axons traveled rostrocaudally in white matter tracts (Fig. 4). These axons were most dense in the ventral white commissure and around the ventral median fissure. Non-varicose axons were also common in the lateral and ventral funiculi in rostral thoracic segments. The density of non-varicose axons declined progressively from rostral to caudal segments.
