Figure 6

The relationship between measured Yv in adjacent small and large vessels. (a) A representative vessel mask with zoomed inset shows that the blood from small vessels will travel into the adjacent large vessel segment. The pink boxes show sample ROI selections to probe the relationship between small vessels and large vessels. The relationship (b) before, and (c) after eddy-current correction for baseline (blue diamonds) and after ingestion of caffeine (yellow diamonds) (N=5). The error bars represent standard deviation across 10 Yv values (5 from Anterior-Posterior scans, 5 from Foot-Head scans).
