Table 1 Physiological parameters before and after saline or quinpirole administration to unanesthetized rats

From: D2-like receptor activation does not initiate a brain docosahexaenoic acid signal in unanesthetized rats

  1. 1Orofacial activity, consisting of head tremors and sniffing was observed for 10 minutes after saline or quinpirole injection. All quinpirole-treated rats exhibited characteristic head tremors and sniffing activity within 2 minutes of drug injection. Values are mean ± SD of n = 6 saline and 7 quinpirole treated rats per group. **P < 0.01 compared to before quinpirole injection by paired t-test.
