Neutral crest cells give rise to the schwann cell sheaths of the peripheral nerves, so I guess its dorsal columns.
Everything else in the spinal cord comes from the neutral tube.

dorsal columns

cos they receive their input from peripheral nerves..hence there is POST SYNAPTIC DEGENERATION.. due to lack of input.
