Figure 4From: The spinal antinociceptive effects of cholinergic drugs in rats: receptor subtype specificity in different nociceptive testsDose response curves for intrathecal McN-A-343, all data All ECT (neck and tail) and TFL values recorded in the rats that received intrathecal doses of McN-A-343 that subsequently had positive lignocaine tests. Values for each testing site and modality have been combined at each dose of McN-A-343 and shown as means ± SEM; n = 20–25.Back to article page
