Hemoencephalography (HEG)

HEMO

Overview

Hemoencephalography (HEG) is a method of monitoring changes in frontal cerebral blood circulation and oxygenation. As a biofeedback tool, therapists measure self regulation of cortical activation. HEG biofeedback can be a superior method for ADD/ADHD, depression and migraine training when compared to EEG training at the front of the head. It is also much simpler to set up and monitor than EEG. There are two types of HEG training: passive infrared (pIR) HEG and near infrared (nIR) HEG.

Education

The BFE currently offers a small selection of live online or recorded presentations that discuss hemoencephalography. Below is a small selection of available content. For a more complete listing, click here.

HEG Online Class or HEG Online Class Recording: learn all about hemoencephalography (HEG) theory, performing a successful training session and useful clinical tips in this online, interactive class or from the class recordings.

Introduction to the HEG Suite Webinar Recording: get a quick introduction to all facets of the BFE’s pIR and nIR HEG software suites in this recording.

Software

The BFE has developed hemoencephalographic assessment and training software, based on the original designs of Jeff Carmen, Ph.D., and Hershel Toomin, Ph.D., with the aid of several clinicians, including Dr. Ernesto Sholomo Korenman. The difference in the methodologies goes back to the two different types of HEG training – pIR HEG or nIR HEG. Click on the links below to learn more about the techniques developed by experts in the field.

pIR HEGPassive Infrared Hemoencephalography (pIR HEG) by Dr. Ernesto Korenman

This suite enables the measurement of blood perforation in the frontal part of the brain via the amount of heat given off, which is better know as passive infrared hemoencephalography (pIR HEG). As the frontal lobe works harder, more oxygenated blood is brought to region and the skin surface temperature increases which is what the pIR HEG thermogenic sensors detect. This method is developed and brought to popularity by Jeff Carmen, Ph.D.

NIR HEGNear Infrared Hemoencephalography (nIR HEG) by Dr. Ernesto Korenman

This suite enables the measurement of blood perforation and oxygenation in the frontal part of the brain via the injection of red and infrared light into the tissue and re-measurement of the amount of light that is reflected back out, which is better know as near-infrared hemoencephalography (nIR HEG). As the frontal lobe works harder, more oxygenated blood is brought to region and the ratio of red to infrared light changes based on the amount of blood present which is what the Meditech nIR HEG sensors detect. This method was developed and brought to popularity by Hershel Toomin, Ph.D.
