Figure 7

NIN data visualization. (A) Schematic of the NIN sensor region. (B) Sensor space display, with time series plots positioned at the source (Sx) and detector (Dx) locations. Individual time series plots show time on the x-axes and oxy-hemoglobin (red) and deoxy-hemoglobin (blue) concentrations on the y-axes. Yellow highlights the interval in which the subjects were engaged in a sequence learning task. A scale bar in the center indicates that the task period was 32 s in duration. Concentration is shown in arbitrary units (relative concentration), due to an unknown scattering factor. (C) Example NIN image of task-related oxy-hemoglobin regression parameter Z-scores from (B) corresponding to the rectangular area shown in (A). (D) The same data as (C), masked at a statistical threshold of p < 0.05 corrected for multiple comparisons. Color bar for Z-scores in both (C) and (D) appears in (D). Plots B–D were made with NinDISP using matplotlib.
