Combined DASL-fMRI experiment. (a) t-score map of the BOLD functional response to bilateral stimulation of the rat forelimbs. Robust activation regions are present in both left and right primary somatosensory cortices. (b) Combined DASL-fMRI time-course. The functional hemodynamic is superimposed on top of the DASL experiment. (c) Data averaged into a single DASL cycle, obtained after fitting and filtering of the DASL curve. Stimulation periods are indicated by the horizontal bars underneath the hemodynamic response. The control phase of the DASL cycle displays a robust BOLD response, while the labeling phase shows the mixing of the functional BOLD and CBF contrast in anti-phase to each other.
