    Brain waves are classified by frequency:  alpha, beta, gamma, delta and theta.  Gamma are the fastest at up to 300 Hz.  Beta are associated with wakeful alertness and are at 12-30 Hz.  Alpha, 8-12 Hz, are connected with the "Ganzfeld" state which could be described as restful daydreaming.  Theta are at 4-7 Hz and associated with meditation and imagination.  I think they're unique to humans, or possibly all apes.  Finally, delta waves are slow, associated with dreamless sleep, have a frequency of 1-4 Hz, and are, fascinatingly, sometimes still present after death for up to ten minutes.
