Abstract

The plasma membrane of a nerve cell separates the extracellular mM Ca2+ concentration, [Ca2+]o,from the intracellular μM Ca2+ concentration, [Ca2+]i. When activation of the neuron takes place an action potential flows along the axon towards the nerve ending, and depolarization of its membrane causes the entry of Ca2+, which triggers the fusion of synaptic vesicles with the plasma membrane and the subsequent release of neurotransmitters (Fig. 1).
