The area described on the previous slide that contains all the unique wavefunction information is referred to as a Brillouin Zone.

There are an infinite number of Brillouin zones, and they are universally referred to according to the rules above. Essentially each time a Bragg Plane is crossed, the next Brillouin zone is entered.

In the figure above, the yellow square comprisesthe first zone, the purple comprises the second zone, and so on.
