Abstract:
21 albino rats were used. The origin of the noradrenergic (NA) fibers in the septum was studied with a simultaneously combined retrograde fluorescent tracing and histofluorescence method. The results revealed that the NA neurons projecting to the septum were in A_1, A_2 and A_6 groups. The projections of A_1 were bilateral, But A_2 and A_6 projected dominantly to the ipsilateral septum, with a few to the contralateral. Retrograde labeled NA cells were localized in the rostrodorsal part of A_6 group, and scattered over the whole rostrocaudal length of A_(1,2) groups. No labeling was seen in A_4 and A_7 groups. In five of the animals, retrograde labeled NA cells were occasionally observed in A_5 group. In addition, some scattered labeled non-NA neurons were seen in the raphe and the ventrolateral reticular formation of the rostral medulla.
