Figure 3From: Inflammatory nociception diminishes dopamine release and increases dopamine D2 receptor mRNA in the rat's insular cortex The figure represents a positive correlation between paw withdrawal latency (PWL) and (A) dopamine, (B) DOPAC or (C) HVA. The dots in orange depict the measurements three hours after the carrageenan injection, the green ones 1 h afterwards and the black ones show the status prior to inflammation. Notice that as the release of dopamine and its metabolites increases, so does PWL and vice versa (Pearson correlation, dopamine r = 0.862, p < 0.001; DOPAC r = 0.873, p < 0.001; and HVA r = 0.818, p < 0.001).Back to article page
