Figure 3From: A [14C]iodoantipyrine study of inter-regional correlations of neural substrates following central post-stroke pain in rats Key brain regions that showed significant differences in pixel counts between the CPSP and sham groups. The results were obtained by differential subtraction between the CPSP and sham groups. The signals in the cortex, thalamus, hypothalamus, and amygdala in the CPSP group were significantly higher than in the sham group, and the signal in the ventral basal nucleus in the CPSP group was significantly lower than in the sham group.Back to article page
