Figure 1

Representative injection sites of CTB, in 2 guinea pigs, are shown in the rostral (A) and caudal levels (C) of the NPO. Photomicrographs B and D correspond to the dashed areas indicated in the rostral (A) and caudal (C) levels of the NPO, respectively. Each coronal section includes the injection site (darken area), centered within the boundary of the NPO of a given animal, with the area of dispersion of CTB granules indicated by the hatched area (in A and C). Abbreviations: CTB, cholera toxin B-subunit; DTgP, dorsal tegmental nucleus, posterior part; IC, inferior colliculus; LDT, laterodorsal tegmental nucleus; LL, lateral lemnicus; LSO, lateral superior nucleus; Me5, mesencephalic trigeminal nucleus; ml, medial lemnicus; Mo5, motor trigeminal nucleus; NPO, nucleus pontis oralis; P, pyramid; PPT, pedunculopontine tegmental nucleus; scp, superior cerebellar peduncle; Tz, nucleus of the trapezoid body; tz, trapezoid body.
