I think it is the choroid plexus....not for sure though Afferent sensory fibers (those returning to the brain from the periphery) synapse first in the posterior horn of the spinal cord, ascend one to two levels and decussate (cross over) at the anterior white commissure before their axons migrate to the anterior or lateral spinothalamic tracts. These then synapse again in the thalamus for integration before they go on to the post-central gyrus - the sensory cortex - and other sites in the cortex.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
