Figure 1

CVLM and MLF injection sites with associated spinal injection sites. (A–D) Shows an experiment to double-label cells with axons passing through the CVLM and (E–H) are taken from an experiment to label axons of cells passing through the MLF. (A,E) Show CTb injection sites in coronal sections of the medulla. (B,F) Show injection sites mapped onto outline diagrams (Paxinos and Watson, 2005). Black, the core and gray, spread of CTb. (C,G) Fluorescent images superimposed upon dark field images of the same sections illustrating Fluorogold injection sites at L1–2. Drawings showing the locations of spinal injections (black) are shown in (D,H). Note the spread of Fluorogold within the gray matter surrounding the injection. 4V, 4th ventricle; 12, hypoglossal nucleus; CVLM, caudal ventrolateral medulla; Gi, gigantocellular reticular nucleus; Gr, gracile nucleus; LRt, lateral reticular nucleus; MLF, medial longitudinal fascicle; py, pyramid.
