Unveil Hidden Secrets
in Your Brain
Using the Quantitative EEG

The following vignette is based upon a true story but is disguised for purposes of confidentiality:

The Case of Hidden 8-Hz Brain Waves

A 43-year old stroke victim sought neurofeedback treatment one year past the brain incident. The left side of the body, particularly the leg, lacked motor control. The quantitative EEG (QEEG) was able to pinpoint several areas in which to concentrate training for motor recovery.

The big surprise was that "hidden" in the frontal regions of the brain was an unmistakable, 8-Hz rhythm suggestive of ADD difficulties. When the examiner reported this to the client, the client "nearly fell out of the chair." This explained the client's life-long difficulty in concentrating and learning. It opened up the possibility of solving an enduring problem the client had not even thought of addressing.

Sometimes the QEEG reveals features of your brain's performance that are completely unexpected. This enables the neurofeedback trainer to target the specific dysregulation patterns of your brain to enhance the likelihood of success.

Why Should You
Take the QEEG?

The quantitative EEG (QEEG) is a special analysis procedure used to uncover dysfunctional electrical patterns in your brain. It is not used to pronounce a diagnosis such as ADD or depression though it certainly may reveal patterns associated with those diagnoses. Instead, it is used to develop neurofeedback training protocols in order to optimize the functioning of your brain.

You may wish to seek neurofeedback training for a wide variety of psychological or physiological challenges without resorting to medication. You can find out more information about neurofeedback training by clicking on the link below:

What is Involved When You
Take the QEEG?

The QEEG requires you to put on a cap with 19 sensors embedded in the fabric. You also wear a sensor on each ear. These sensors measure tiny electrical voltages generated by your brain. To get accurate readings, it is advisable to wash your hair and scalp vigorously without conditioner prior to your session.

Eight samples of brain wave recordings are collected during your session. Two of each occur while you
  • close your eyes
  • look at a stationary object
  • read from a book or magazine
  • perform some basic math problems
After these data samples are collected, you are excused and will certainly want to wash your hair again. The measurements are later analyzed using an advanced, state-of-the-art, software package named SKIL. This analysis reveals precise information regarding:
  • specific frequencies in each area of your brain
  • how your brain patterns compare to a database of normal people
  • how well different areas of your brain coordinate with each other
  • training protocols likely to enable your brain to function better

To find out the relevance of SKIL assessment for your individual challenges and needs, call (714) 985-4700 now to schedule a FREE phone consultation.

Where Can You Locate
Additional Information about the QEEG?

The QEEG is very technical in nature and well beyond the scope and purpose of this web site. However, you can find further information as noted below:

What is Quantitative EEG?

David Kaiser, Ph.D., one of the developers of SKIL, has posted a 37-page technical discussion of the QEEG. Dr. Kaiser's bottom-line conclusion in that paper is:

Quantitative EEG is a powerful and sensitive tool for identifying maladaptive brain activity patterns - that is, bad brain habits.

The SKIL analysis program is extremely technical and beyond the scope and purpose of this web site. You can find further information about SKIL as noted below:

SKIL 3.0

All QEEG analysis programs make certain assumptions about the brain, recording artifact, reference sites, mathematical transformations of raw signals, etc. in arriving at final conclusions. SKIL has more versatile analysis options transformations than any other existing package. More information can be found by clicking on the following link:

Unexpected signals sometimes lurk hidden in the squiggly lines of the EEG. If you don't have the proper tools to unmask them, they will remain hidden. The Brodman analysis offers one such example.

SKIL's Brodman Capability

No other program has the Brodman analysis capability that is found in SKIL 3.0. If you click on the link below and scroll down to the section entitled "The Magic of Biomathematics!", you will see how the Brodman analysis can reveal a hidden sindusoidal wave that other software programs would miss.
