Non-uniform changes in nerve-terminal calcium homeostasis during aging.
Currently unpublished studies indicate reduced rates of calcium clearance from the transmitter release sites in presynaptic terminals of some, but not all, motor nerves in aged rats. Further evidence indicates that deficits in calcium regulation may not necessarily underlie observed age-related changes in evoked transmitter release.
