Brainwaves state like all waves are measured in following two ways….. That are Brainwave Frequency / state is the first state and the speed of the electrical phase… Frequency is measured in cycles per second (cps), ranging from .5 cps. to 38 cps. The brainwave is which is measured in Hertz (Hz) and the second measure is amplitude….. Throughout the day and night our brain is producing a complex mix of electrical patterns or waves depending on your physical and mental activity. There are basically four main and several not so commonly used brainwave states corresponding to certain frequency ranges of the brainwaves. Your brain is constantly producing all the brainwave states simultaneously with one state being dominant depending upon our mental and physical activities at that time.
