Introduction

Summary

Synapse activity and related ionic mechanisms: Calcium ions flow into the presynaptique zone, through voltage-dependent channels, inducing exocytosis. Sodium ions flow into the postsynaptic neuron though receptors specific for a given neurotransmitter, inducing membrane depolarization.

Goals

• To understand nerve signal transmission at the level of an excitatory synapse.
