Fig. 6From: Decreased haemodynamic response and decoupling of cortical gamma-band activity and tissue oxygen perfusion after striatal interleukin-1 injectionChange in gamma- and beta-band power peak amplitudes. Graphs showing the averaged changes in the log amplitude of the a gamma-band frequency and b beta-band frequency activity peaks at the onset of the stimulus in groups before and after striatal injection. The asterix show the significance of the change within each group compared to the pre-injection values. Mean ± SEM; ** p < 0.01; *** p < 0.001; repeated-measure one-way ANOVA before normalisation to pre-injection time point with Bonferroni post-tests versus Pre Back to article page
