Figure 2: Increased T2 relaxation time in the hippocampus of infected hamsters in MRI slice 5. Top, false colour T2 maps of infected (left) and uninfected (right) hamsters collected at 61 days post injection (dpi). Bottom, mean relative 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.
