case_images: Figure 2 shows the waveform of [oxyHb] during the cognitive activation of the word fluency task. On day 4, the centroid value of the grand average in the central region was 68.6 seconds (Figure 2), and the NIRS waveforms showed an [oxyHb] reincrease in the posttask period (CH 34, 35, 36, 39, 45, 46, 47, and 49; Figure 2), which is characteristic of schizophrenia. On day 77, the NIRS waveforms turned to a negative pattern (Figure 2), which was defined by an integral value of the grand average in the central region <0, whereas there were [oxyHb] reincreases in the posttask period (CH 33, 41, 42, 43, 44, 51, and 52).

case_images: We defined the patterns of NIRS waveforms using the grand average waveforms in the frontal region (CH 25-28, CH 36-38, and CH 46-49; Figure 3) and two simple visual indices, integral value, and centroid value.
