Named rhythms have characteristic frequency ranges and wave forms and are seen in specific areas of the brain. As a rule the slower waves are larger and cover greater distances -- a function of the number and type of neuronal connections involved in production of the wave.

Follow the links to understand a little of the function and localization of specific wave forms.
