HEG (Hemoencephalography)

HEG (hemoencephalography) is the study of blood flow in the brain. More specifically, it is the study of voluntarily controlled blood flow or oxygenation in chosen brain modules. Blood brings oxygen and the basic nutrient, glucose, at life sustaining levels to all parts of the brain. Our brains have an amazing ability to supply extra blood preferentially to those modules in current use.

Several instruments have been developed which use blood flow to the brain as a marker for neurofeedback training.  We use near infrared HEG (nirHEG) developed by Hershel Toomim. This instrument shines light through the skin and skull to assess the color of brain tissue. Oxygenated arterial blood is red, deoxygenated venous blood is blue. Increased demand for nutrition results in faster blood flow and redder blood in the tissues.  We use this instrument for a wide range of conditions, particularly with traumatic brain injury or cases where the frontal lobes are not functioning at optimum levels.  The brain is trained to increase oxygenation by using computer-based interactive games and DVDs.


The Roshi/Brainlink is the newest generation in neurofeedback equipment and is the only device available that combines both conventional cognitive biofeedback and photostimulation technology. This combination, plus the capability of instantaneous, real time feedback is what makes the ROSHI/BRAINLINK protocols unique. These features allow the therapist to stimulate and train the brain in ways that are simply not possible with any other technology. This translates into faster progress for the client and, in the case of peak performance work, results so far unmatched by any other system.

One of the most popular units in our neurotherapy inventory of devices is the Roshi. Developer Chuck Davis calls the Roshi a tool to shift consciousness and quiet the mind in a way that is similar to that seen in meditation. Many people remark after using the Roshi that they feel unusually quiet and clear headed. The unique stimulation system allows for relative long periods of stimulation using either visible light or magnetic pulsations. The Roshi stimulation can also be combined with EEG biofeedback either using it’s own software or in tandem with other software packages.

Several practitioners have developed very effective protocols for using the Roshi with different conditions. The following summary by D. Corydon Hammond Ph.D. describes the response of clients to treatment with the Roshi as follows:

“The very first Roshi session produced positive changes, and within five sessions the patient reported feeling less depressed and more energetic. At the conclusion of thirty training sessions, objective testing documented dramatic reductions in depression, somatic symptoms, overemotionality, anxiety, rumination, and fatigue that describes the use of the Roshi with depression.” Journal of Neurotherapy Volume 4, 2000-2001

pRoshi, Personal Roshi

Chuck Davis has recently introduced a new Roshi device that allows for powerful neural stimulation without need for actual EEG recording. This new device, called the pRoshi, appears to be useful in shifting the connectivity of different regions of the brain and produces a general sense of quiet centering.

The pRoshi can be used in conjunction with many of our other therapuetic modalities (like  Hemoencpalography) where it can significantly boost the brains ability to perform at an optimum level.
