HEG, or HemoEncephaloGraphy, is training aimed at increasing blood levels and blood oxygenation to improve the metabolic capacity of parts of the brain. It’s primarily done on the pre-frontal cortex, which is the executive center of the brain. One of the major benefits of HEG over EEG training is that it does not measure electrical signals, making it unaffected by electrical activity from muscle movements such as eye blinks. This feature makes HEG particularly helpful for training areas of the brain that have difficulty with planning, organizing, attention, impulse control, or other executive functions. HEG training can significantly aid in making brain cells more efficient by ensuring they have ample blood supply, thereby increasing their oxygen and glucose availability and enhancing their firing capability when necessary. It is simpler to start with and hard to make many mistakes in working with, thus serving as an excellent entry point for new trainers or a valuable addition for experienced EEG trainers. There are two types of HEG systems: pIR, which stands for Passive InfraRed, developed by Jeff Carmen, and nIR, which stands for near InfraRed, developed by Hershel Toomim.
