    Fig. 1. <t>fNIRS</t> sensor montage registered to the head for participant #2144 (upper-left). Emitters and detectors are colored red and green respectively. The remaining graphics show the corresponding summed sensitivity map for the subject, illustrating the relative sensitivity of the fNIRS sensor montage (shown on a square-root scale) for detecting chromophore changes across the cortical surface. Anterior (A), posterior (P), superior (S), inferior (I), left (L) and right (R) are labelled for reference.

    Fig. 2. Volume to surface projection of task-related activity measured during right-handed finger tapping for a representative participant (#2144). fNIRS results are shown here for oxyhemoglobin. Each slice image shows the volumetric activity from a different view (axial, sagittal and coronal) centered on motor cortex (MNI coordinates x: −40.72, y: −22.70, z: 60.54), together with the corresponding surface projection. Anterior (A), posterior (P), left (L) and right (R) are labelled for reference.

    Fig. 4. Single subject comparisons of the spatial correspondence between task-related fNIRS and fMRI activity mapped to the cortical surface during the Motor task for three representative participants drawn from the first, second, and third quartiles of fNIRS/fMRI overlap (#2014, #2132, #2144, labelled as I, II, III respectively). For all comparisons, the fNIRS sensitivity threshold was set to 1 % of the maximum total sensitivity and the amplitude threshold (p-value) was set to the average values across participants (p < 0.0599) that maximized the spatial correspondence with fMRI during the Motor task. Anterior (A), posterior (P), left (L) and right (R) are labelled for reference.

    Fig. 3. Single subject (#2144) fNIRS channel level results for the Motor task. Each topographic plot shows the T-score for task-related activity in each channel. Channels with significant task-related are denoted by solid-colored lines (p < 0.05, critical T = 2.47 via Benjamini-Hochberg procedure). Channels whose task- related activity was not statistically significant are denoted by dashed lines. Plot insets show the block average responses and standard deviations during the task period (green shading) for the channel with the largest task-related response. Time courses have been smoothed by a 3-second centered moving average (mean) for visualization.

    Fig. 5. Single subject comparisons of the of the spatial correspondence between task-related fNIRS and fMRI activity mapped to the cortical surface during the Visual task for three representative participants drawn from the first, second, and third quartiles of fNIRS/fMRI overlap (#2014, #2132, #2144, labelled as I, II, III respectively). For all comparisons, the fNIRS sensitivity threshold was set to 1 % of the maximum total sensitivity and the amplitude threshold (p-value) was set to the average values across participants (p < 0.0405) that maximized the spatial correspondence with fMRI during the Visual task. Anterior (A), posterior (P), left (L) and right (R) are labelled for reference.
