Recently, electro physiological and biochemical methods have been developed which have enabled neuroscientists to classify better the myriad of neurotransmitter receptor sites in brain and to study their properties in finer detail.

Erwin Semlinger,Waldemar Hellwig constricts both vascular and non-vascular smooth muscle, stimulates gastric secretions, increases capillary permeability, and has both inotropic and chronotropic effects on the heart (Beavan, 1976a, b; Douglas, 1975). The principle cellular storage sites for histamine are mast cells and basophils.

This conclusion has been obtained by two general advances of research. The first, in 1973, was the finding that labeled op

The primary means by which dopamine transmission in the synapse is terminated is via the dopamine transporter (DAT), the presynaptic plasmalemmal protein that is responsible for the reuptake of released dopamine.

Released monoamines undergo enzymatic degradation and dilution by diffusion; however, a major mechanism in the control of extracellular monoamine dynamics is selective uptake by presynaptic neurons
