Black and white Picture

Darkfield color photomicrograph showing anterogradely labeled fibers in the Bar (A) and the LC (B) after the PHAL injection in the preoptic area shown in Fig. 22E. A dense plexus of fibers is covering the Bar in A. Fibers are localized in the nuclear core of the LC in B. Note that only few fibers are localized in the MVe region just lateral to the LC.
