Catecholamines histochemistry

In contrast, the content of norepinephrine is substantially lower than the content of dopamine (28). Catecholamine-containing neurons do not innervate the parenchymal cells of the bovine parathyroid gland only an occasional norepinephrine-containing neuron terminating upon a blood vessel is demonstrated by fluorescence histochemistry (22). 

The findings obtained by Dahlstrom and Fuxe in 1964 indicated the existence of a monoaminergic innervation of the cerebral cortex without a thalamic relay, but this idea seems initially heretic. However, methodological improvements of catecholamine histofluorescence with the sensitive glyoxylic acid histochemistry (Lindvall and Bjorklund, 1974a,b), together with the development of new techniques in experimental and chemical neuroanatomy mentioned earlier (see Section 1.1) convinced the neuroscience community that transmitter-characterized subcortical systems can innervate the cerebral cortex directly.
