Hemoencephalography (HEG) biofeedback as a method of stress control among healthy subjects
Journal Title: International Journal of Humanities and Social Science Invention - Year 2018, Vol 7, Issue 1
Abstract
Hemoencephalography (HEG), noninvasive brain imaging which is used to measure local changes in hemoglobin concentrations and spatial image reconstruction. The resolution of HEG, may be complementary to other imaging methods based on the hemodynamic response such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET).This method can be used for imaging activation and functional connectivity in the prefrontal cortex of healthy subjects during the demonstration of colorful words (in the proper meaning) in the Stroop test. A form of neurofeedback named hemoencephalography (HEG), using HEG, may improve the brain function by training the subject to increase blood flow in the prefrontal cortex (PFC). Neurofeedback is an effective tool for self-regulation, useful for achieving better self-knowledge and enhanced cognitive skills. Visual evoked potentials (VEP) are the brain’s responses to visual stimuli displayed on a computer screen, such as a reversing checkerboard pattern, color pictures or words. Analysis were prepared using LORETA software for EEG. Oxygenated and deoxygenated arterial blood levels before (BEF) and after (AFT) HEG session were presented.
