from "Neuroscience" ed. Dale Purves.  third edition.  sinauer publishers.  

"Another peptide hormone essential for neural induction is sonic
hedgehog (shh).  Shh is thought to be particularly important for
differentiation of neurons - including motor neurons - in the ventral
portion of the neural tube...expression of shh mRNA is limited to the
notochord and floorplate of the developing spinal cord.  This
localized expression is thought to establish a gradient of secreted
shh peptide extending throughout most of the ventral spinal cord."
