 Brainwave pattern


 Brainwave Cycles Per Second  Mental states & associated processes
  GAMMA  30Hz to 60Hz or 40Hz to 99Hz*** There continues    to be some disagreement in regards to where      GAMMA Starts (30 Hz or 40Hz) *** Compassion, Empathy, Decision making under stress, higher brain functioning and processes, influences sensory organization processing and integration. believed to strongly influence the organization and interpretation of sensory data. Believed to have a strong impact on social consciousness and right and wrong. Enhanced self awareness and insight. GAMMA frequencies are found naturally in higher amounts in long term practitioners of various forms of meditation. Believed to enhance the ability to achieve goals.

  ALPHA    8Hz to 12Hz Associated with lighter meditative states. associated with super learning. More relaxed. Relaxed yet alert but not necessarily engaged in active processing. Ready to respond, positive thinking, creative problem solving.
