Secretory vesicles are localized in specific compartments within neurosecretory cells. Morphometric, cytochemical and electrophysiological techniques have allowed the definition of secretory Vesicle compartments. These are different pools in which vesicles are in various states of releasability. The transit of vesicles between compartments is not random, but an event controlled and regulated by Ca2+ and the cortical F-actin network. Cortical F-actin disassembly, a Ca2+-dependent event, controls the transit of secretory vesicles from the reserve compartment to the release-ready vesicle pool. Furthermore, the recent development of new technical approaches (patch-clamp membrane capacitance, electrochemical detection of amines with carbon-fibre microelectrodes) has now permitted us to understand the kinetics of single vesicle exocytosis.
