Figure 23E

Darkfield color photomicrograph illustrating anterogradely labeled fibers in the LC and surrounding structures after a CTb injection in the perifornical nucleus dorsal to the fornix at the level of the dorsomedial hypothalamic nucleus. Note the terminal-like dots in the nuclear core of the LC. More terminal-like labeling is visible in the medial parabrachial nucleus and the lamina between the LC and the fourth ventricle.
