All About Brainwaves

Your brain creates simple electricity through an electrochemical process measured in the form of brainwaves. Brainwaves occur at different frequencies depending on what the brain is doing. By measuring these frequencies, using qEEG, it is possible to see where the brain is functioning less optimally. Brainwave activity occurs on a continuum from slow to fast wave frequencies. For measurement, these brainwave frequencies are separated into five categories based on their repetitions per second (Hz) or cycles per second (cps).

The brainwave frequency bands used for clinical purposes are:

  • Delta (0.5-4 Hz) – Deep dreamless sleep. Healing, regeneration, repair, pain relief. Cortisol decreases. DHEA, serotonin, melatonin increase. Access to unconscious mind. Loss of bold awareness. Babies in womb and infants in this state.
  • Theta (4-7.5Hz) – Deep Meditation, relaxation. Insight, intuition, creativity. REM sleep, dreaming. Inner peace. Reduced consciousness. Hypnopompic & hypnagogic states.
  • Alpha (7.5-12.5Hz) – Physically and mentally relaxed. Being in a flow state. Quietly flowing thoughts. Stress reduction. Efficient focus and learning.
  • Beta (12.5-30Hz) – Normal awake and alert consciousness. Thinking actively or analytically. Problem solving or making decisions. Busily or excitedly focusing on an action.
  • Gamma (30-100Hz) – High level perception and processing. Peak state of mental awareness. Cognitive enhancement. Memory recall, leaning. Transcendental states.

      Thank you. I am glad you liked it. It has been my personal experience that knowledge of brainwave states enhances a person’s ability to make use of the specialized characteristics of those states: these include being mentally productive across a wide range of activities, such as being intensely focused, relaxed, creative and in restful sleep.

      Our brains contain about 100 Billion neurons (nerve cells) which send information to each other, both electrically and chemically through the 800 trillion ever changing connections. And neurons come in a wide variety of configurations too. Wow!

      My best guess would be Theta. What do you think?
