Relationship between presynaptic calcium current and postsynaptic potential in squid giant synapse

R Llinás et al. Biophys J. 1981 Mar.

Abstract

The relationship between calcium current and transmitter release was studied in squid giant synapse. It was found that the voltage-dependent calcium current triggers the release of synaptic transmitter in direct proportion to its magnitude and duration. Transmitter release occurs with a delay of approximately 200 mus after the influx of calcium. A model is presented which describes these relations formally.
