Our Brainwaves & Meditation.
A crash course on Brainwaves. Whether we are mentally active, resting or asleep, the brain always has some level of electrical activity. We can study & monitor the frequency and location of electrical brain waves through the use of EEG, (electroencephalography). EEG electrodes are placed in standard locations of the scalp using a custom made hat. In the late 1960’s and 1970’s it was learned that it was possible to recondition and retrain brainwave patterns. Some of this work began with training to increase alpha brainwave activity to increase relaxation, while other work originating at UCLA focused on uncontrolled epilepsy. This brainwave training is called EEG biofeedback or neurofeedback. Brainwaves occur at various frequencies.
The classic names of these EEG bands are alpha, beta, theta and delta & more recently Gamma has been discovered. Delta – sleep state (0.5 to 4Hz) (0.5 to 4 cycles per second) Theta – between sleep and awake (4 to 8 Hz)(4 to 8 cycles per second) Alpha – relaxed state (8 to 12Hz) (8 to 12 cycles per second) Beta1 – focused concentration (13 to 30Hz) (1330 cycles per second) Beta2 – alert state Beta3 – very alert, vigilant Beta4 – Hyper vigilant Theta : Relaxed: Indicates deep relaxation and occur more frequently in highly experienced meditation practitioners. Alpha : Calm: Allows the mind to relax and get ready for different mental tasks. It is also a state important for contemplation, planning, inspiration and learning facts fast. Beta1: Focused: Allows paying attention to a specific task, while offsetting distractions. Beta2: Alert: Allows fast response when the need to react quickly is required. Gamma brainwaves have been associated with peak performance states.
Beta can be highly alert but it also can be a highly stressed state, like being in dental pain. Alpha can be a very relaxed state while reading, right before sleeping but many experienced mediators can be in Alpha state for most of the day. Theta when asleep is when you are dreaming, also known as REM, or Rapid Eye Movement.
If awake in Theta one is in a very deep meditation where out of body experiences can occur along with visions of other dimensions. Delta brainwave state is when you are deeply asleep & not dreaming, it is the most restorative state where your body heals. In very rare cases a person may be in a delta state while awake, in fact monks who have mastered meditation can even bring their bodily functions to almost flat line, appearing brain dead on an instrument but very much alive. Feelings of a oneness with the universe can be experienced in this state if awake.
We are never really in one brainwave state at any given time, we are always in a combination of 2 or 3. We categorize what brainwave state we are in by being predominately in one or another. So you could say Beta is your predominate waking brainwave state. As seen above each brainwave is associated with a frequency, these frequencies of states correlate with every possible human experience, thought & feeling we ever have.
It is possible to train your brain to be in a certain frequency through sound & the frequency following effect that sound has on the mind. That is our natural tendency for our minds to resonate with certain sounds.
Alpha brain waves: 8-14 Hz Relaxation and meditation. It is achieved during meditation and numerous energy healing techniques to create a deeper state of relaxation and wellbeing. Often used by Reiki healers. Creativity and learning is easily accessed and processed in this state.
Theta brain waves: 4-8 Hz This is the important one. In this frequency the mind experiences feelings of bliss, happiness and compassion and is capable of heightened learning, healing, and growth. Experienced frequently by shamans during ceremonies, well practiced mediators such as Tibetan monks.
It is this frequency that we can learn to enter to influence the dominant subconscious part of ourselves that is normally inaccessible to our conscious mind and make powerful life enhancing changes.
Delta brain waves: 0-4 Hz The slowest of all brainwaves and is associated with deep sleep. People with a heightened sense of intuition or psychic abilities are able to consciously access this brainwave
