Color darkfield photomicrographs of frontal sections showing the distribution of anterogradely labeled fibers at the level of Barrington's nucleus (C) and the LC (D) after a PHAL injection in the area 1 of the frontal cortex. Note that only a few anterogradely labeled fibers are localized in the LC itself.
