Nerve impulse transmission: generation, propagation and the synapse

What this note covers

1. Resting neurons maintain an electrochemical gradient
2. Threshold triggers an all-or-none action potential
3. Local currents propagate the impulse along an axon
4. Myelin enables saltatory conduction
5. Chemical synapses transfer information between cells
6. Trace transmission across generation, propagation and transfer
