Brain Waves

Brain Wave Measurement and Frequencies

The fact that the brain emits measurable frequencies has been known since the beginning of the last century. How it does this is not known. In the 1960s, it was discovered that a person could exert some control over these frequencies and the term “biofeedback” was coined to describe this process. With the advent of increased computing power and a deeper understanding of the brain, the research focus is now on “neurofeedback.” The year 2010 saw the first hard evidence of neuroplastic changes occurring directly in the brain after voluntary control of brain rhythms. (T. Ros et al., Endogenous control of waking brain rhythms induces neuroplasticity in humans)

The range of brain frequencies emitted by the human brain has been divided up and named as follows:

  • Delta (0 to 4 Hz)      deep night time sleep
  • Theta (4 to 7 Hz)      dreams at night and trance state of somnambulism
  • Alpha (8 to 12 Hz)    background brain activity in the waking state. (Named alpha because it was the first one discovered by Hans Berger in 1908.)
  • Beta (12 to 30 Hz)  awake, alert, focused
  • Gamma (30-100 Hz)    certain cognitive or motor functions

The diagrams below are a 3D representation of brain wave patterns recorded using an IBVA recorder. Across the width of the diagram is the frequency from delta on the left to gamma on the right. Time is recorded in the length of the strip – each diagram being about a five-minute segment of time. Amplitude is shown in the height in microvolts.

The first diagram is that of a client in a non-focused state and shows a random distribution across the ranges. The second diagram shows the coherence and specificity in Jack’s brain as he works with the Reconnective Healing® energy frequencies. The left and right hemispheres of the brain appear in separate windows. The left window represents the left hemisphere of the person. Recordings made in September 2010.

Note: These EEG (Electroencephalography) experiments were done by Jean-Charles Chabot, a hypnotherapist specialized in Life Between Lives spiritual hypnosis, who uses the IBVA recorder in his practice. (

Note: Jean-Charles and I carried out these experiments without knowing whether such an experiment had been done before. On October 29, 2012, reading Ervin Laszlo’s Science and the Akashic Field, (p. 152-153) I discovered a description of a similar experiment showing the same result and giving a bit more information about being in a state of receiving energetic healing. Laszlo’s book was first published in 2004, a new edition appeared in 2007 both from Inner Traditions in Vermont.

“An experiment carried out in the presence of this writer took place in southern Germany in the spring of 2001. At a seminar attended by about a hundred people, Dr. Günter Haffelder, head of the Institute for Communication and Brain Research of Stuttgart, measured the EEG patterns of Dr. Maria Sági, a trained psychologist and gifted natural healer, together with that of a young man who volunteered from among the participants. The young man remained in the seminar hall while the healer was taken to a separate room. Both the healer and the young man were wired with electrodes, and their EEG patterns were projected on a large screen in the hall. The healer diagnosed the health problems of the subject, while he sat with closed eyes in a light meditative state. When the healer found the subject’s areas of organic dysfunction, she sent information designed to compensate for it. During the approximately fifteen minutes that the healer was concentrating on her task, her EEG waves dipped into the deep Delta region (between 0 and 3 Hz per second), with a few sudden eruptions of wave amplitude. This was surprising in itself, because when someone’s brain waves descend into the Delta region, he or she is usually in a state of deep sleep. But the healer was fully awake, in a state of intense concentration. Even more surprising was that the test subject exhibited the same Delta-wave pattern–it showed up in his EEG display about two seconds after it appeared in the EEG of the healer. Yet they had no sensory contact with each other.”

IBVA recorder

IBVA is a brain-computer interface for monitoring brainwaves sold internationally since the early 1990s. IBVA reveals inner state changes in human brainwaves (EEG) in realtime giving 3D interactive control. IBVA stands for “Interactive Brainwave Visual Analyzer.” It could be called an electronic mirror for the mind. The brain’s EEG is measured and translated into 3D coordinates using its amplitude (as microvolts) and speed (in units of Hertz) grouped into the standard bandwidths known as Delta, Theta, Alpha, Beta, and Gamma. IBVA simultaneously displays the left and right sides of the prefrontal cortex.
