Passive Infrared Hemoencephalography (pIR HEG) and Infrared Imaging of the Prefrontal Cortex

HEG neurofeedback (hemoencephalography) is photon based brain biofeedback. No skin prep required! Compared to EEG, it is immune to eye roll artifacts, and easily targets the prefrontal cortex. There are two kinds of HEG. nir HEG and pIR HEG .
