Branching projections from subcoeruleus area neurons to medial preoptic area and cervical spinal cord revealed by double retrograde neuronal labeling.
In this study we utilized a double retrograde axonal tracing technique to investigate the possible existence of collateralized axonal projections of subcoeruleus area neurons to both 'medial preoptic area (MPA) and cervical (C1-C3) spinal cord'. Following microinjections of fluorescent tracers (Fast blue (FB) and Diamidino yellow (DY) within MPA and C1-C3, substantial numbers of FB and DY single-labeled neurons as well as FB-DY double-labeled branched neurons have been found within subcoeruleus area.
