Figure 3: Increased T2 relaxation time in the hippocampus of infected hamsters in MRI slice 6. Top, false colour T2-weighted MR images of infected (left) and uninfected (right) hamsters collected at 61 days post injection (dpi). Bottom, mean T2 relaxation time in the hippocampus expressed as a percentage of the mean T2 relaxation time in the thalamus, +/- standard error of the mean (s.e.m.). Solid black line: infected; broken black line: mock-infected; solid grey line: control hamsters.
