D2‐like agonist quinpirole in the PVT promotes emergence from isoflurane anesthesia. (a) Schematic representation of the implantation site of the guide cannula (black) above the PVT. The infusion cannula (gray) is within the PVT. (b) Pharmacological experiment protocol for emergence time. (c) DAPI stained coronal brain sections showing the track of the guide cannula (white arrow heads) above the PVT. Dashed white line indicates the outline of the PVT. (d and e) Scatter plot of emergence time. Microinjection of quinpirole (4 mM) facilitated emergence, in contrast, raclopride (2 mM) delayed emergence time. Data shown as mean ± SD (n = 7). **p < .01, *p < .05. Data were analyzed by one‐way ANOVA with post hoc Bonferroni multiple‐comparison test. Scale bar: 500 µm in c
