ABSTRACT
Functional near-infrared spectroscopy (fNIRS) is an optical imaging method which monitors the brain activation by measuring the successive changes in the concentration of oxy- and deoxyhemoglobin in real time. In this study, we aimed to investigate the functional connectivity in the prefrontal cortex (PFC) during a modified version of the color-word matching Stroop task among schizophrenia and healthy persons. fNIRS data were band-pass filtered using a wavelet algorithm with frequency range of 0.003-0.08Hz. Partial correlation (PC) values were computed for each stimulus condition. Our analysis shows that the functional connectivity of PFC is highly relevant with the cognitive load and it is different from healthy to schizophrenia person.
