Arterial Spin Labeling (ASL) fMRI: Advantages, Theoretical Constrains and Experimental Challenges in Neurosciences
Figure 5
Tracking functional changes over one month. (a) Comparing baseline CBF on day 1 (indicated by first red horizontal line in upper panel, illustrating experimental design), and baseline CBF on day 30 (second red line in upper panel) shows stability over time. Middle panel shows the whole brain maps on day 1, and lower panel shows whole brain maps on day 30. (b) Comparing acute CBF changes induced by visual or motor stimulation on day 30 to baseline CBF on day 1 (as illustrated in the upper panel) is similar to acute changes induced by visual or motor stimulation on day 1 to baseline CBF on day 1. Middle panel shows the whole brain maps of day 1 stimulation to day 1 baseline, and lower panel shows whole brain maps of day 30 stimulation to day 1 baseline. Maps show similar motor and visual cortex activations. (Note that this is a modified version of Figure 3 in Borogovac et al. [55]).
