Localization of pontine carbachol injection sites. Various symbols in A show the centers of carbachol injections placed on the corresponding closest standard sections of the pons (22). Circles, carbachol injection sites in the six rats with combined injections of prazosin and methysergide into the XII nucleus; triangles, sites in the six rats with only prazosin injected into the XII nucleus; diamonds, sites in the six rats with only methysergide injections. All carbachol injections were placed within a discrete region of the dorsal pontine tegmentum. (B) Carbachol injection site in one of the rats used in the present study, as seen in a coronal section of the pons. The darkened area in the dorsomedial pontine tegmentum (arrow) represents deposition of the blue dye injected with carbachol. LDT = laterodorsal tegmental nucleus; PO = nucleus pontis oralis; scp = superior cerebellar peduncle; VT = ventral tegmental nucleus.
