Figure 2 Illustration of the hemodynamic responses in different region-of-interest regions during the verbal fluency task in patients with predominantly positive symptoms of schizophrenia (PSZ) and those with predominantly negative symptoms of schizophrenia (NSZ). The brain regions analyzed include the left and right inferior frontal gyrus (IFG-L and IFG-R), middle frontal gyrus (MFG-L and MFG-R), and superior frontal gyrus (SFG-L and SFG-R). The graphs show the mean concentrations of oxygenated hemoglobin (HbO) and deoxyhemoglobin (HbR) over time.
