Concepts

1. Understand how an action potential travels down an axon.

2. Understand how a neuron sends a signal to another neuron. What happens at the synapse?

3. Why are neuron membrane polarized? What causes depolarization and repolarization?

4. What is the difference between voltage-dependent and chemical-dependant ion channels.

5. What is the difference between excitation and inhibition?
