Figure 2
Mean Z-spectra from the (a,b) hippocampus and (c,d) cortex acquired with saturation B1s of 0.5 and 0.75 µT show a lowering of CEST contrast (an increase in signal) after stress, mainly in the cortex. The ranges with the largest differences are marked with blue rectangles. The solid lines are the average Z-spectra for all the animals in the group, whereas the shaded areas illustrate one standard deviation.
