Gamma

Gamma represents a pretty small share in most brains, and the overall band has increased from 40 to 42 Hz.

Jay Gunkelman did a fascinating presentation at FutureHealth in which he reviewed studies on gamma and its role as the binding frequency going back several decades. He showed quite impressively that gamma appears to be an adjunct to this state–not the driver as is often stated or implied in recent NF writings. His candidate for the true key player was slow cortical potentials (on which gamma “rides”) produced by the brain stem–the on/off switch for arousal and consciousness.

If you are really training gamma (which I usually do training synchrony), it shouldn’t have much of an effect on high beta.  The gamma state is more of a communication connection.  High beta is more like rumination, anxiety, pressure.
