From: Inflammatory nociception diminishes dopamine release and increases dopamine D2 receptor mRNA in the rat's insular cortex

Figure 1

The graphs show extracellular levels of (A) dopamine, (B) DOPAC and (C) HVA in the insular cortex. The data are expressed as the percentage of their respective basal levels. Notice that group with inflammation (which received an intraplantar injection of carrageenan) shows a decreased percentage in the levels of dopamine and its metabolites when compared with the control and thermonociception groups. Repeated measures ANOVA, Dopamine (F = 7.817 p = 0.021, n = 6), DOPAC (F = 11.223 p = 0.002, n = 8) and HVA (F = 6.902 p = 0.006, n = 8).
