Fig. 5.

Arm-cuff occlusion results. An arm-cuff occlusion was performed for 4 min, following 3 min of resting state, and followed by 3 min of recovery. Images were acquired using spatiotemporal modulation of light at 100 fps and processed for oxygenation. Top images show oxygen saturation at three time points during the baseline resting measurement, the occlusion, and after the release. The saturation of a point in the hand (blue square) is shown in the plot below. Time points of the above images are indicated by arrows.
