The Effects of Endocrine, Synaptic and Nutritional Inputs on Catecholamine-Containing Neurons
The catecholamine norepinephrine is probably utilized as a neurotransmitter by a small but important fraction of the neurons in the brain (Wurtman, 1966). The cell bodies of most of these neurons are localized within the brain stem; their terminals are present in high concentrations within the structures of the limbic system and the septo-hypothalamo-mesencephalic continuum (Dahlström & Fuxe, 1965). The medial forebrain bundles may contain ascending and descending multisynaptic noradrenergic systems in addition to the “classical” monosynaptic pathways identified by his to-chemical fluorescence techniques.
