Summary

We discuss the fundamental units of the nervous system: neurons and supporting cells, which are formed from radial glial cells, progenitor cells that divide to generate new neurons, which then migrate to their destination. An understanding of the anatomy of neurons and their function enables us to decipher how information travels within the nervous system and how neurons communicate with each other through synapses to form networks capable of performing sophisticated and complex tasks. We then discuss how ions traverse the cell membrane and the critical role ion channels play in establishing resting membrane potential, and how action potentials are generated and propagated along the axon.
