It is one of four brain wave patterns (compare BETA rhythm; DELTA rhythm; theta rhythm).In electroencephalography, rhythmic oscillations in electric potential occurring at an average rate of 10/sec.In electroencephalography, oscillations in electric potential occurring at a rate of 8½ to 12 per second.
