Gamma (30-100Hz): The most recently discovered range is Gamma which is the fastest in frequency at above 40Hz (some researchers do not distinguish Beta from Gamma waves). Although little is known about this state of mind, initial research shows Gamma waves are associated with bursts of insight and high-level information processing.
In a nutshell, there are five major brain wave ranges: Beta (12-30Hz) is present in normal waking consciousness and is heightened during times of stress; the Alpha brain wave (7.5-14Hz) in deep relaxation; Theta (4-7.5Hz) in meditation and light sleep; and the slowest, Delta (0.5-4Hz) in deep dreamless sleep and transcendental meditation. The less recognised Gamma is fastest (above 40Hz) and associated with sudden insight. The optimal level for visualization is the Alpha-Theta Border at 7-8Hz. It is the gateway to your subconscious mind.
