Branching axons from subcoeruleus area project to the nucleus raphe pontis and hypothalamic zona incerta, as studied with the double fluorescent retrograde tracing technique.
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 raphe pontis nucleus and hypothalamic zona incerta. Following microinjections of fluorescent tracers (Fast blue (FB) and Diamidino yellow (DY] within raphe pontis and zone incerta, substantial numbers of double-labeled branched neurons have been found within the subcoeruleus area.
