Figure 3 Changes in Skin SNA and Vascular Resistance in Subjects With 2CDel322-325 Allele

Intranasal cocaine caused a similar increase in skin sympathetic nerve activity (SNA) and skin vascular resistance in both groups of subjects. Dexmedetomidine (Dex) reversed effects of cocaine on SNA and skin vascular resistance similarly in both groups. Data are mean ± SE. *p < 0.05 versus baseline, p < 0.01 versus baseline.
