Site specificity of circling behavior evoked by muscimol (200 pmol). Values represent group mean values ± SEM of peak circling in the presence of tail lift. Peak circling occurred within the first 20 min after microinjection. Muscimol (200 pmol in 220 nl, shaded bars) was injected (in separate groups of rats) into one of five sites. The five sites, in order of appearance on the graph from left to right, are 1 mm anterior to the STN injection site (EPN;n = 6), STN (n = 7), 2 mm dorsal to the STN injection site (n = 4), 0.5–1.0 mm posterior to the STN injection site (n = 4), or directly into the SNpr (n = 4).Asterisks indicate significantly different from respective controls (clear bars) (Student'st test; p < 0.05);cross indicates significantly different from STN and SN muscimol injection groups (ANOVA and Fisher's post hoc;p < 0.05).
