Figure 3

Camera lucida drawings of coronal sections through the caudal pons and medulla oblongata from rostral to caudal (a–i) illustrating the pattern and distribution of anterogradely labeled descending fibers following PHA-L injection into the KF (see inset j, filled circles reflect neurons which have been filled with PHA-L, and therefore represent the probable neurons with projections). Figure published with permission of Horst Herbert, Tübingen, Germany. Orientation: Panels a–i are from rostral to caudal transverse sections through the pontomedullary brainstem.
