Primary afferents enter the dorsal horn and immediately diverge within ALL the funiculi. What is the next step in the pathway?
1) Sends stimulation several segments cranially and caudally to allow the stimulus to participate in the intersegmental reflexes
2) Bilateral axonal projections are diffusely present in the white matter of the spinal cord (decussations occur throughout the spinal cord in this pathway)
3) Reticular formation in brain stem (wakefulness center)
4) Multiple cortical and subcortical destinations
