Investigating physiology of untruth in cerebral cortex by functional near-infrared spectroscopy (fNIRS)

Abstract

Physiological measurement has been deeply investigated in microenvironment. The physiology on molecular or biochemical levels is examined to diagnose disease in early state. With new brain imaging techniques such as multi - channel near - infrared spectroscopy (NIRS), the functions of the cognitive brain activities can be determined. In this study, the relationship between specific physiology of brain cortex and psychology of untruth is assessed through measurements of the changes in concentration deoxygenated hemoglobin (HHb) and oxygenated hemoglobin (HbO2)by multi - channel NIRS. Moreover, we found the complex combination at prefrontal cortex (Cz ) is related to physiology of truth and untruth. © 2013 IFMBE.
