FIGURES

Figure 6E

Photomicrograph illustrating anterogradely labeled fibers in the nuclear core of the LC after a CTb injection in the ventrolateral part of the periaqueductal gray. Note that the lamina between the LC and the fourth ventricle (on the left of the figure) contained more fibers that the nuclear core of the LC.
