Thermal Passive Infrared HEG (pirHEG) & Optical Near Infrared HEG (nirHEG)
HEG (hemoencephalography) is a method of monitoring and regulating blood flow in the brain. Through this method, voluntary control over blood flow or oxygenation in specific regions in the brain is regulated. Since the brain needs to supply extra blood to those modules in current use (blood provides oxygen and nutrients, glucose to various parts of the brain) the regulation of blood flow is extremely important in proper functioning of various brain regions.
Use of HEG for activating the pre-frontal cortex as well as other lobes, has been very useful in the treatment of various disorders including ADHD, Migraine Headaches, and other neurobehavioral disorders. This method is also very useful in conjunction with Neurofeedback in improving auto-regulatory functions of the brain.
Thermal Passive Infrared HEG (pirHEG) and Optical Near Infrared HEG (nirHEG) are the two methods of HEG that use thermo-modulations and changes in brain tissue color as a method of measuring blood flow and oxygenation in the brain.
