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.

- To understand nerve signal transmission at the level of an excitatory synapse.
Transmission of impulses between neurons occurs at their point of junction, called the synapse. It is estimated that about 40% of the total surface of a neuron is composed of synapses. These have…
