Figure 2From: Persistent changes in spinal cord gene expression after recovery from inflammatory hyperalgesia: A preliminary study on pain memoryClustering of genes differentially expressed at 24h and 28d. Data presented as mean ± SEM. Genes were classified by SOM; n = number of genes in each cluster. * – p < 0.001 compared to control, #- p < 0.001 compared to 24h group.Back to article page
