This chapter focuses on astrocytes. In the last fifteen years, the status of astrocytes has changed profoundly from a cell scaffold and metabolic-trophic reservoir offering neurons a necessary, yet only passive, support to a full actor, working in collaboration with other glial cells and with the surrounding neurons by the continuous exchange of chemical messengers including glutamate, a classical neurotransmitter. Astrocytes as neurosecretory cells, stimulus-secretion coupling in astrocytes, and the role of regulated secretion from astrocytes in brain physiology are discussed.

Keywords: astrocytes; glial cells; neurotransmitters; brain; neurosecretory cells
