Intracellular and extracellular calcium ions in transmitter release at the neuromuscular synapse.

Abstract:

:The theme of this presentation has been to show that the control of transmitter release at the neuromuscular synapse is achieved by extracellular and intracellular calcium. For the fast information transfer represented by the end-plate potential, the electrochemical gradient for calcium across the presynaptic membrane and the associated calcium conductance seem to play the primary role. For slower processes such as tetanic and posttetanic potentiation, the combined effect of both sources for calcium determine the amount of transmitter liberated.
