the distribution of the neuropeptide calcitonin gene-related peptide ( cgrp ) was studied in relation to the known subcortical somatosensory pathways and contiguous systems in the central nervous system ( cns ) of rats by using peroxidase histochemical methods in order to relate zones of immunoreactivity ( ir ) to cytoarchitecture .
