Figure 6.

(a) Time course curves of paired t-values of hemodynamic response. The t-values for the paired t-test were calculated from the difference in hemodynamics during trials of left-hand and right-hand use. The t-values of ΔHbO and ΔHbR for each of the eight sessions were drawn with red and blue lines, respectively. The dotted lines in each frame indicate levels of p = 0.05. (b) Color-mapping of t-values onto the subject’s anatomical MRI. The t-values for ΔHbO of the first session using a food well of 20 mm 5 s after task onset are depicted. Arrows indicate the positions of “hand knob” in each hemisphere.
